Dolphin has become slow recently. In particular, adding or moving a bookmark in the Places panel has a delay of several seconds. To reproduce, create a new bookmark in Places or move an existing bookmark up or down in the Places panel. There is a delay of a few seconds. Previously, there was no noticeable delay. I now experience these delays 100% of the time. Just now I timed it and there is a delay of about 5-6 seconds before the moved bookmark appears moved, then there is a delay of another second or so before Dolphin's GUI is responsive again. Also, if I leave Dolphin open all day, even normal navigation from location to location also becomes very slow. To reproduce, navigate to any location using Dolphin. There is a delay of several seconds before Dolphin refreshes to show the new location. During this time the Dolphin UI is unresponsive (Dolphin appears frozen briefly). Previously, there was no noticeable delay. I only experience this if Dolphin has been open for a while. If I close and reopen it, I do not get the very long delay when navigating to a new location. I'm running KDE on Arch. Here's some system info: plasmashell --version: plasmashell 5.12.5 dolphin --version: dolphin 18.04.0 Linux 4.16.6-1-ARCH #1 SMP PREEMPT Mon Apr 30 12:30:03 UTC 2018 x86_64 GNU/Linux The previous time I looked at my version, I had plasmashell 5.12.3 (a couple months ago). Dolphin was fine in that version. So the problem started after that version, but it may have appeared before my current version. I first noticed it several weeks ago. Nothing about my system has changed other than normal Arch updates.
We have 12 desktops running the latest version of KDE / Plasma / Dolphin from the Arch Linux repos. All are currently on dolphin 18.04.0. Today I went around to several of those desktops and I can report a new observation. Those without any bookmarks in the Places panel seem to respond quickly when adding a new bookmark or moving a bookmark. But those with a larger number of existing bookmarks exhibit slowness both when adding a new bookmark and when moving an existing bookmark up or down the order within Places. This slowness is new with a recent update. My sample size is small, but it does confirm that the issue is not limited to a single computer. Does this warrant changing the status to confirmed?
On the affected machines, is ~/.local/share/user-places.xbel incredibly long? Like, 1000+ lines long?

A good portion of that length is due to devices that are added automatically by the system. I don't use those or even want them shown in Dolphin's Places. Can I manually edit ~/.local/share/user-places.xbel to remove all the devices I don't want? (Dolphin doesn't provide the option to remove them, only to hide them.) Thanks

I edited ~/.local/share/user-places.xbel to remove all the automatically added or obsolete entries and the file was reduced to about 650 lines. I opened Dolphin and moved one bookmark up one place in the Places list. Even with the smaller file, the operation was still slow (requiring about 3 seconds to complete). After this simple operation, ~/.local/share/user-places.xbel increased to 997 lines and many of the entries I had removed were restored. The automatically restored entries are all of this type: <separator href=...."> <info> <metadata owner="http://www.kde.org"> <UDI>/org/kde/fstab/....</UDI> <isSystemItem>true</isSystemItem> <IsHidden>false</IsHidden> </metadata> <metadata owner="http://freedesktop.org"> <bookmark:icon name="network-server"/> </metadata> </info> <title>... on server</title> </separator> I do not need any of those in Places. These include 20 automatically added "Remote devices" and 7 "Devices". I have 35 of my own bookmarks and those are all I need. After the first test, repeated tests (moving a bookmark in Places) also require about 3 seconds. (Until a recent Dolphin change a few weeks ago, this operation was nearly instant.) The file ~/.local/share/user-places.xbel remains at 997 lines after these repeated tests, as I'm sure you would have expected. Adding or removing bookmarks in Places is not the only function that is slow now. I experience extensive slowness with operations in the file panes under some circumstances. However, so far I am unable to give exact steps to reproduce it. It seems to happen when I have had Dolphin open all day. Hope that info helps. Thank you. Dolphin is the best Linux file manager!
Thanks for all the testing!
As another test, I have left Dolphin open for the last two days. Now clicking on any GUI element shows several seconds of delay and refreshing the file panes is very slow. "top" shows high CPU usage for Dolphin in response to these routine GUI actions. Closing Dolphin causes 100% CPU usage for several seconds. After reopening Dolphin, normal responsiveness returns for most actions (but not for bookmarks in the Places panel).

Please start dolphin from gdb and press CTRL+C when it gets stuck. Then copy here the stacktrace from gdb.

Prior to a few months ago, this did not happen. I would leave Dolphin open for weeks (or months) at a time on my desktop computer. Since a change a few months ago, I now close Dolphin each night. This keeps the GUI acting relatively responsively. For this test, I have been running Dolphin from gdb for two days without closing it. Today I can notice a slight decrease in GUI responsiveness (very slight), but the messages in gdb are exactly the same. There are no additional error messages or anything that looks abnormal. I'll continue this for another week or so and see if any messages change and how much Dolphin slows down over time. So far the messages I see are similar to these. There are not many of these: Empty filename passed to function kf5.kservice.services: KMimeTypeTrader: mimeType "" not found inotify_add_watch("/home/user/Downloads/MyTemp") failed: "Permission denied" org.kde.knotifications: Audio notification requested, but sound file from notifyrc file was not found, aborting audio notification Access to ' "/home/user/workspaces/xyz" ' denied, not owned by root, executable flag not set. UdevQt: unhandled device action "bind" UdevQt: unhandled device action "unbind" And only one message like each of these: Trying to convert empty KLocalizedString to QString. qt.accessibility.core: Cannot create accessible child interface for object: PlacesView(0x5555558f33a0) index: 41 Other than that, the messages are mostly like this: [New Thread 0x7fff81ffb700 (LWP 15125)] [Thread 0x7fff81ffb700 (LWP 15125) exited] org.kde.dolphin: Saving view-properties to ... I would like to fix the permission issues and other issues, but I don't see anything wrong with any permissions. I own the directories mentioned in the messages. And I'm sure these messages are not related to the slow GUI responsiveness issue I am troubleshooting now.
Created attachment 113050 [details] attachment-12417-0.html Here's an update. The Dolphin GUI has gotten very sluggish now (after letting Dolphin run several days without closing it). However, there are no unusual messages in gdb. Right now, copying a file from one file pane to the other exhibits a very slow GUI, but there are zero debug messages associated with this action. Any suggestions for next steps? Does the pmap output below help? (As I mentioned, this GUI slowness is relatively new. I first notice it a couple months ago after using Dolphin for more than 10 years.) $ pmap 33240 33240: /usr/bin/dolphin 0000555555554000 4K r-x-- dolphin 0000555555754000 4K r---- dolphin

One day later and now Dolphin is using over 5 GB of RAM. Specifically, pmap shows "total 5551616K" Is any other information required? If not, I will close and reopen Dolphin to free up all this memory and get Dolphin back to running snappy.
Hmm, what's your usual workflow? Do you open a lot of tabs/windows with many files?

This behavior started a few months ago. I certainly do not "max out" Dolphin in any way. I generally use it only with a couple tabs open. I demand a lot more of Kate, for example, where I keep large projects open all the time. I would say I use Dolphin lightly. BTW, I love Dolphin. I think it is the best file manager on Linux. I'm not here to bash Dolphin. I'm just motivated to provide any feedback I can regarding this issue.
I went ahead and closed Dolphin and reopened it. After that, pmap reports the following memory usage: total 853220K That's down from this amount just before I closed & reopened it: total 5551616K That's a reduction of 4698396 or around 4.5 GB. This is my guess: it looks like Dolphin memory usage grows by 1 GB per day on average and that after a couple days the UI becomes very sluggish.
There have been various memory leaks that were fixed just this week, so it'd be great if you could test again after the release of KDE Applications 18.08 (16th of August). For now, I'll set this report to NEEDSINFO/LATER.
18.08 has been released for about a month now. Have you been able to update Dolphin and test this again? It'd be great to know if you do still experience this issue.

Thank you for helping us make KDE software even better for everyone!
I am running Dolphin 18.08.1 on Arch Linux. The problem still exists for me. To reproduce, let Dolphin stay open for a few days. Then add or remove a bookmark in the Places panel. Dolphin will freeze for several minutes. There are other symptoms of Dolphin being much slower than it was prior to the changes that were made a couple months before I first reported this issue. However, this bookmark test is an easy one to quantify. Previously, there was essentially no delay. Now, adding a bookmark makes Dolphin unresponsive for several seconds, and if Dolphin has been left open for a few days, that delay increases to several minutes. I may have more bookmarks in Dolphin than some people, but it is not an unreasonable number. Back on May 8, we discussed the size of my ~/.local/share/user-places.xbel file. It is currently 1192 lines. Anything else I can tell you?
Following up on my last comment, the issue seems to have gotten a bit worse after 18.08.2. I used to leave Dolphin open for days and weeks at a time, with a number of tabs set up for longer term tasks. Now that I have to close Dolphin several times a day to keep it responsive, I see that Dolphin would benefit from saved/named sessions like those found in Kate.
Running KDE Neon 18.04, since an update sometime in october, I've been noticing huge slowdowns with Dolphin also, I was out of country for a while so I had a big backlog of updates and can't nail down exactly when it started, am currently up to date on all packages. I average 6ish tabs open in dolphin, after some days, maybe only hours of general usage, I can see the dolphin process spike to 100% cpu when I am hovering over files, the animation of hovering over the files is also very lagged like its really struggling, the cpu spiking will stop if i dont move the mouse, and resume as I hover over another file, even simple small txt files. The same behavior is seen when switching tabs as well. I tried closing all tabs down to just 1 and it was noticeably better bug still laggy, only after fully restarting dolphin did I get normal fast performance again. I opened up a bunch of tabs (6) to various folders I work in and was still fast since the restart. I'm a programmer but not experienced in linux development, but this feels like a resource build up occurring that isn't getting cleaned up, causing heavy cpu work just to do basic things. I'd be happy to try debugging or monitoring logs as the issue returns but at the moment I wouldn't know where to start in that regard xD. Software: dolphin 18.08.3 plasma 5.14.4 frameworks 5.52.0 qt: 5.11.2 kernel: 4.15
The issue still exists. Software versions: dolphin 18.12.2 plasmashell 5.15.0 Qt version 5.12.1
I have also been noticing huge slowdowns with Dolphin for a while now. First noticed it around the time this bug was opened. My issues are the same as those already reported here. Previously, I was able to keep Dolphin open. Now I have to close Dolphin after each use. Software: dolphin 19.04.3 plasmashell 5.16.4 Qt 5.13.0 kernel: 5.2
I'm investigating slow UI responsiveness in Dolphin on my desktop & noticed this bug report. I also run Arch Linux. What caught my attention is this part of the report: "In particular, adding or moving a bookmark in the Places panel has a delay of several seconds." That is the same behavior I'm observing. Adding a new bookmark to Dolphin's Places sidebar has a long delay and it causes the Dolphin UI to freeze for this time. The same delay is seen if I edit the item in Places and change its display name, or remove an item. I timed dragging & dropping a local directory onto Places. It took 15 seconds for that item to appear in Places, but Dolphin was still unresponsive for an addition 10 seconds. It was about 25 seconds before I could navigate or use the UI. The delay is almost the same for a name change. Deleting an item from Places seems to require about 15 seconds. Other operations in Dolphin do not appear to be slow, and the overall experience is not slow. There is one thing I notice that it not mentioned by the OP. All KDE file-open dialogs open slowly. It takes about 2 seconds for the file-open dialog to display in Kate or any other application. GTK file-open dialogs are nearly instant. wc -l ~/.local/share/user-places.xbel 1649 I use KDE on a number of different devices. The computer used for the timings mentioned above has 128 GB of RAM, a Samsung Pro NVMe, nVidia RTX 2080 GPU and an Intel i9-9900K. It has 15 NFS shared folders mounted. It has a large & slow internal HDD that is only used for automated backups and I don't open this backup location in Dolphin anyway.
close Dolphin mv ~/.local/share/user-places.xbel ~/.local/share/user-places.xbel.bak open Dolphin The above steps eliminate the slowness. That also eliminates all my Places bookmarks, so it is not a solution. For testing, it does indicate that the comment by Nate Graham (2018-05-08) is looking in the right direction.
I was able to reproduce the bug adding many many entries to my bookmark menu and get a trace: Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1". 0x00007f01b57b2d39 in QObjectPrivate::setParent_helper(QObject*) () from /usr/lib/x86_64-linux-gnu/libQt5Core.so.5 (gdb) bt #0 0x00007f01b57b2d39 in QObjectPrivate::setParent_helper(QObject*) () from /usr/lib/x86_64-linux-gnu/libQt5Core.so.5 #1 0x00007f01b57b3623 in QObject::~QObject() () from /usr/lib/x86_64-linux-gnu/libQt5Core.so.5 #2 0x00007f01b6276257 in QAction::~QAction() () from /usr/lib/x86_64-linux-gnu/libQt5Widgets.so.5 #3 0x00007f01b627628d in QAction::~QAction() () from /usr/lib/x86_64-linux-gnu/libQt5Widgets.so.5 #4 0x00007f01b6403fdf in QMenu::clear() () from /usr/lib/x86_64-linux-gnu/libQt5Widgets.so.5 #5 0x00007f01b76a88e3 in KDEPrivate::KUrlNavigatorPlacesSelector::updateMenu (this=0x564235251f80) at /home/meven/kde/src/kio/src/filewidgets/kurlnavigatorplacesselector.cpp:72 #6 0x00007f01b57ab458 in QMetaObject::activate(QObject*, int, int, void**) () from /usr/lib/x86_64-linux-gnu/libQt5Core.so.5 #7 0x00007f01b572ba29 in QAbstractItemModel::dataChanged(QModelIndex const&, QModelIndex const&, QVector<int> const&) () from /usr/lib/x86_64-linux-gnu/libQt5Core.so.5 #8 0x00007f01b76782b3 in KFilePlacesModel::Private::_k_reloadBookmarks (thi #0 0x00007f01b6a482a4 in ??

And the inner loop of updateMenu is not light. Making adding new places an exponentially slower operation. To solve this issue : 1/ We need to call updateMenu once per update to the model 2/ We need to make the update progress incremental idealy
> I was able to reproduce the bug adding many many entries to my bookmark menu... That's good news. Thanks for your work on this issue. I would like to add an observation. In my case I do not have to add "many many" entries. Dolphin automatically adds entries for all mount points. The mere fact that my system has 15 NFS mounts and more than one local storage device is sufficient to cause this issue with a modest number of my own bookmark entries in Places. If I delete these autogenerated entries from `user-places.xbel`, Dolphin puts them back -- even though I don't need or use them in Dolphin. Maybe it would also help to have an option to tell this code to ignore certain mounts?

Fixing this bug could fix the issue you are describing. If not, it sounds like it is a different bug and we might want to open a new bug with your specific case. Wait to see once this bug is resolved fix your issue before opening a new one. > > If I delete these autogenerated entries from `user-places.xbel`, Dolphin > puts them back -- even though I don't need or use them in Dolphin. > > Maybe it would also help to have an option to tell this code to ignore > certain mounts? Right click on the entry in the place menu > Hide, it's that simple. It works on places groups too, and can be undone using the "show hidden places" of the groups context menu.

That does not remove the items from ~/.local/share/user-places.xbel Instead of "hide" I was suggesting an "ignore" feature that would avoid placing unwanted system mount points in user-places.xbel. The name of the file implies they are user-places, which seems to indicate it should contain only entries the user is interested in. Just my thoughts. Thank you for your work on this issue!
Git commit 60475571926d79ffad90061985f39c3ce9c686d1 by David Faure, on behalf of Méven Car. Committed on 22/05/2020 at 17:53. Pushed by dfaure into branch 'master'. KUrlNavigatorPlacesSelector: only update once the menu on changes Previously the updateMenu function was called twice for each place added/removed.

I look forward to testing git commit 60475571926d79ffad90061985f39c3ce9c686d1. Thanks for the working being done on it. I believe that fix will help with the issue of changes to the Places bookmarks being very slow. In the OP and the comments of this bug report at least two other issues are mentioned: 1. a memory leak 2. Dolphin and KDE file-open dialogs in all KDE applications open slowly. It takes about 2 seconds for the file-open dialog to display in Kate or any other application. The memory leak may not be related to this issue (Dolphin slow for specific operations) so I won't say more about it. However, the Places bookmarks are related to the long delay in Dolphin and KDE file-open dialogs opening up. I state this because when I delete ~/.local/share/user-places.xbel, the issue goes away and these dialogs (and Dolphin) open very quickly. That should be easy to confirm. If you make a large enough bookmarks list to see the problem on adding or editing a bookmark, you should also see file-open dialogs become slow to come up. My question is should I make a separate bug report or is this likely related to the fixes being done here?

Separate always for different things. As bug fixer We don't have time to read N comments, the more specific bugs the easiest and quickest it is to solve. And use good naming "Dolphin has become slow recently" could have been more precisely "Creating of moving places freezes dolphin for seconds" Then let bug triage group the bugs if needed. Like here there could have been a bug reported for File dialogs too and we would have marked one of the two duplicate of the other.
