Sometimes I think it may be useful to someone to just post some observations. I had occasion to reboot Mandrake 9.0 three times lately: (Incidental observation: two occasions were intentional -- wanted to see if a reboot would restore my performance -- kmail seems to slow down the system more and more the longer it runs -- don't see anything suspicious on top (i.e., no excessive CPU usage, no excessive memory usage), but if I shut down kmail, the whole system is more responsive, system is still OK when I restart kmail, but over a few days, the system just gets slower and slower. Third reboot was due to a power failure longer than my UPS could ride out)
Here is the main observation -- after two of those boots, top performed strangely -- once I started top, the first update of top showed low CPU state usage (like 0.3% user, 0.7% system). The next update of top (which I assume now counted top) showed state usage totalling 100% (or almost) between user and system, and similarly on each subsequent update. (I hadn't noticed that behavior with top before the first reboot, but sometimes I'm not ready to trust my memory of behaviors that I can't reconfirm.) Now, after the third reboot, behavior is back to what I expect -- low state usage except when I do something that makes it spike. Wierd! (Am I running Windows by mistake??) I'm not really / actively looking for a fix (at least for the top behavior) -- if somebody knows why this occurs and has a simple fix, I'd probably try it. I assume the kmail performance problem is something that will be fixed in future versions of kde (whatever the problem is). Randy Kramer
