I guess you missed the original post:

That was after a long idle period when everything was really slow, response to
mouse clicks, keyboard events, etc. Click on a background window, wait 5-6
seconds for it to start to come to the foreground. That kind of thing (and no
As you can see, there is plenty of free swap space. You can also see the
PAGING and DISK utilization stats are off the charts. There was no user

copying, no unpacking, rsyncing, etc. The disk usage you see there was in
response to simple mouse clicks (like to raise a window) and/or keyboard
like typing in a text terminal.
If its not kernel swap, its something horribly askew in 9.04 (at least on my
system). The same system has run 7.04, 7.10, and 8.04 just fine. 8.10 was a
trainwreck (because intel chipset debacle). 9.04 is better, but it is a system
that requires rebooting occasionally to be functional (at least the desktop).
This is like one step forward, and 3 steps backwards. The notion of rebooting
to maintain system integrity just rubs me the wrong way. This is a microsoft
