I'm a system and network admin. One of my users has a Duo 230
([*]specifications below) that has been having slowdown problems.
Leaving the Duo on for several hours causes it to slow down
unacceptably. It can take 10-15 seconds to change applications. During
this time it is completely hung.  If he reboots, the problem goes away
(For a while). It seems the system is getting itself into a wedged
configuration.

He's re-installed System 7.1 and rebuilt the desktop. Neither of these
have helped. 

It's possible that it's network-related, he uses Eudora which checks his
email every 10 minutes (over Ethernet). He hasn't checked to see if this
problem occurs while undocked (he's docked most of the time). 

Little to no non-Apple inits, I don't want to start yanking the rest
unless I know that might *really* be the problem. 

He hasn't tried zapping the PRAM, I have advised him to do that next.

Anyone who has ideas, I'd love to hear about them. I'd call Apple, but
I've found they're best to call during the week (it's Sunday evening).
