--- Comment #11 from MountainX <davestechs...@gmail.com> --- 1. I did further testing on two desktop computers. I used the same user-places.xbel file on both. (Copying the file from one computer to the other seems to work fine.) The large version of that file increases Dolphin startup time by at least 400% on both computers. On the faster computer, Dolphin startup time goes from 0.49 seconds to 2.045 seconds. (The effect is greater on the other computer.) Deleting the user-places.xbel file results in dramatic speed up. Using a file with more entries (including entries on NFS mounts and with custom icons) results in dramatic slow down. This is confirmation of what I reported earlier after more testing on the second computer. On a computer where Dolphin performs very snappy I was able to make it become very sluggish simply by copying the larger user-places.xbel to it (without making any other changes). 2. The slow startup is not just the first time. With Dolphin open, opening a new window is just as slow as the first startup. File dialogs become consistently slow, so it seems whatever is slowing Dolphin down is not being cached. 3. Next I looked at the effect of NFS mounts separate from my Places bookmark entries. I started by deleting user-places.xbel, and let Dolphin create the minimal version. As mentioned, I have 10 NFS mounts defined in /etc/fstab. I timed Dolphin startup time. Then I removed all NFS mounts from /etc/fstab on one computer and umounted all those mounts, and again let Dolphin create a minimal user-places.xbel (which is now very small). Removing all NFS mounts from the computer makes a further improvement in Dolphin start up time. This reinforces the value of an option in Dolphin to ignore (do not read, access) certain entries in user-places.xbel. Many of mine are never opened in Dolphin, but I have to pay a cost for them every time I open Dolphin or any KDE file dialog. 4. Next I deleted Dolphin settings (~/.config/dolphinrc) and tested that way. Then I manually recreated all my original Dolphin settings (split pane view, etc.). I did not detect any effect on Dolphin startup time. I believe I can rule out dolphinrc as being responsible for a significant startup delay. Bottom line: it's user-places.xbel, NFS mounts and maybe folder icons. And the effect of these things on Dolphin startup time KDE file dialogs is huge. -- You are receiving this mail because: You are watching all bug changes.
