Re: Question on scrollkeeper-update

[Chris Chabot <chabotc reviewboard com>]

Ok, so if there is no Disk activity, that means everything is done in 
memory at that moment. So one would expect _CPU_ activity!!! This is 
also not the case (as i said a couple of times already). There is no IRQ 
being triggers, no HD activity, no CPU activity, no high memory stress, 
its doing _nothing_ for quite a few seconds.

(forgive my over emphesis, but we seemed to be going on loops here ;-)
