Description northon_patrick3 2016-05-10 13:05:58 UTC
Dolphin is now very slow when browsing NTFS partition. You can see it load sub folders information one by one very slowly. It will sometimes freeze for minutes. It is visible when using the folder panel or detailed view.

This is a very recent regression as it was working a few days ago on Fedora 23, fully updated. I have tested on multiple machines. Other file managers don't have the problems. It happens whether it is a USB drive or an internal drive.

Reproducible: Always

Steps to Reproduce:
1. Browse any NTFS partition, preferably one with a lot of data.

Actual Results:  
Sub folders information load very slowly (Size field, icon to expand a folder).

Expected Results:  
Load fast like it was before.

I tested the latest version of Dolphin from git repository and it is working again, at the time of this writing. So I supposed it has been fixed?
Comment 2 Edmund Kasprzak 2018-02-26 19:33:49 UTC
Currently, I also can't recreate it, looks like it's fixed now.

Can you confirm it's still working correctly for you?
Comment 3 northon_patrick3 2018-02-27 02:20:37 UTC
It still happen on Fedora with the official package (fully up to date at this time). It doesn't happen on Ubuntu. Is it compiled differently on Fedora?
Comment 4 Edmund Kasprzak 2018-02-27 08:35:41 UTC
I'm sure there is some difference (as a general thing in various distributions)

What version of Fedora, Plasma and Dolphin are you currently using?

Does it still work fine in other file managers?
And happens with various drives (internal/usb)?

Can you test it with a new user (to check default settings of KDE/dolphin)?
Comment 5 northon_patrick3 2018-02-27 10:20:17 UTC
My Fedora is fully updated, version 27. It work fine in other file managers, save Konqueror which I assume is using the same thing. It happens on any drives (internal, usb, ssd or not). I did try on a freshly created user. I tested it on multiple machines.
Comment 6 Edmund Kasprzak 2018-02-27 13:31:38 UTC
One more question - multiple machines, all with fedora 27?

You think that maybe you could find some time in a near future to use Neon LiveCD/LiveUSB and check how it looks in a different distro?

There needs to be something specific in your case, as I'm using Kubuntu 17.10 and openSUSE 42.3 on my laptop and everything seems to be fine for my internal ssd (2 ntfs partitions), one external hdd (also 2 NTFS partitions) and I also formatted my pendrive as NTFS in Windows 10 - it's all fine when I access it from doplphin Kubuntu/openSuse.

Is there anything specific that you think could be in your situation?
Comment 7 northon_patrick3 2018-02-27 13:56:40 UTC
Yes, all on Fedora 27. I already tested with Ubuntu (again, latest version at this writing) and it's working. I suspect it's something specific to Fedora and it's been present for almost 2 years. I'll try openSUSE livedvd.

This contains the build log for dolphin on Fedora 27. Maybe there is something in the way it's compiled.
Comment 8 Edmund Kasprzak 2018-02-27 14:01:06 UTC
Thanks for confirming that.
If it's working on Ubuntu for you, then it's not a KDE issue in general, but something done by Fedora, making this a DOWNSTREAM problem.

All I can recommend for you is to raise it in fedora bugs, including a comment that it's working correctly in a different distro.
