Description Brodey Dover 2010-01-05 23:29:44 UTC 
Version:            (using KDE 4.3.4)
OS:                FreeBSD
Installed from:    Unspecified BSD

Dolphin uses /tmp to transfer files. The original indicator of an issue was that the PC-BSD /tmp (700MB) was filling up way before an 800MB file could be transferred successfully using SMB. Afterwards, increasing the size of our /tmp we still noticed VERY slow performance transferring the file, ~300KB over WLAN but System Monitor displayed a throughput of 2.0MB/s+.

Eventually /tmp would reach maximum capacity and display a file read error, the info center would respond by saying the transfer stopped. However, System Monitor will still display that packets are being sent at to the host at full speed.

Investigating /tmp reveals that there are multiple temp files being used by dolphin with the .part extension and an ever increasing file size.

and

both seem to report the same issue.

Removing the information panel does indeed cure the problem all together.

I see. The solution would probably be to disable the Information Panel for 'slow' file systems.

However, something similar has been done for previews on 'slow' files ystems some time ago, which caused a lot of trouble because it's not easy to determine if a file system is slow or not.

Resetting assignee to default as per bug #305719

On Linux, I'm no longer to reproduce the behavior of /tmp filling up while the Information panel is shown using Dolphin 16.12.3 or 17.08.0. Let me know if you can still reproduce the issue on FreeBSD using one of these more recent versions of Dolphin, and I'll re-open the issue.
