When you are faced with this "slowness" is there also a heavy disk I/O?

I have a similar issue here where it sometimes takes up few seconds for a 
seemingly trivial task. like opening the kmenu or clock settings or ... But 
this seems to be also related to another bug (atleast in [K]Ubuntu) where the 
system really becomes painfully slow when there is concurrent disk I/O. There 
is not much processor load during these times but "system activity" reports 
several "disk sleeps".
