Boottime is worked on and shutdown time difference didn't strike me as worth 
to look. But application start is something that needs to looked at if it's so 
noticable as in your case.

The problem is I can only fix what I see and honestly I can't see the major 
slow down you see, so I checked what differences are there and there is one 
huge - Tango icons cache. But I can't say if it's creating the problem you 
see.

What I would like you to do: install blktrace into your opensuse VM and
run the following test:
blktrace -o - /dev/sda6 | blkparse - > gimp.log in a root shell
and then do from a user shell:
export LD_DEBUG=statistics
time gimp

I press Ctrl-Q as soon as I see the tip of the day window appear, gimp will 
start finish and then quit.

As gimp quit, press Ctrl-C in the root shell and save the log. If you send me 
the log, I'll mail you a processed version of it with a tool to analyze 
something, so please don't change the VM after that too much.

Greetings, Stephan
