login/launching programs very slow

I upgraded from 42.1 and my system seems very slow, login takes about 20 to 30 seconds to load the desktop and opening a Konsole window takes about 10 seconds. I posted another thread about Kile freezing up the system as well. I think these are both related and an artifact of left over garbage in my home directory. Creating another user and logging in only takes about 5 seconds, and launching Konsole for example takes about half a second, compared to about 10 under my own profile. I deleted everything in /home/user/.cache and /home/user/.kde4/cachexxx and tmpxxx but that doesn’t seem to have affected anything, at least not permanently. Deleting files from the /home/user/.kde4/cachexxx etc. directories, logging out and logging back in again does speed everything up. However, once I reboot, I’m back to the sluggish performance. Anyone have any suggestions as to what may be causing this?

Thanks.

Nevermind, after some more testing, the other user account slowed down to the same level as mine, so I guess it’s normal. You can ignore this thread, or delete it.
