KDE - Slow startup - Cache rebuild on each reboot

Like some others I am not happy with the duration of KDE startup. To me it takes approx. 1 minute (Core i5, 64bit):

• approx 35 secs for first icon (disk/hdd) on splash window

• approx 5-15 secs for next three icons where it seems spending most time on forth icon (desktop)

• another 10-20 secs on 5th icon (kde)

My hard disk is in use during all of this, i.e. it seems time spent is for IO

Getting same results whether or not Nepumuk is enabled (Startup Service & System Settings).

Plain logout/login takes just 10 seconds.

As suggested in KDE forum  I had a look at my at my KDE cache directory. Two cache files are updated on each reboot: plasma_theme_default.kcache and icon-cache.kcache

$ ls -lhtr /var/tmp/kdecache-jochen/
total 112M

-rw-r--r-- 1 jochen users  11M 14. Jan 19:19 icon-cache.kcache

KDE forum suggests that should not be the case and might be down to distribution (see earlier link). Anyone aware of this and any chance to disable cache rebuild during reboot? Does not happening when logging off/back in.

No update. In fact, it seems it got worse. Hoping QT5 will make a change. No longer suspecting cache files however.

Re: KDE - Slow startup - Cache rebuild on each reboot

I had an issue where It would take exactly 1 minute 35 seconds to go from the arch logo in refind to task bar operation recently. Found that when I had first installed arch, my wired card was called enp5s0 and all of the networking stuff was set up to enp5s0. Somehow or another, it got changed to enp6s0 and kde/systemd/networkmanager was having a conniption fit trying to use enp5s0, but would eventually settle for enp6s0. I changed the link named network@enp5s0.service to network@enp6s0.service and almost everything seems to be alright now.
