We have just recently installed SuSE SLES8 under our VM3.1.0 system, and are experiencing some performance issues. Our Realtime monitor reveals that Linux is utilizing approx 65% of our CPU cycles, but we really have nothing running. I was told by our Linux guy to give it lots of memory, so I defined it with 1G. I'm wondering if this is my problem, or if I might have something else set up wrong. We have Tivoli Directory Server 5.2 fixpack1, DB2 ver 8.2, and websphere express 5.1, but it is not configured yet. We have just installed these products, and they are not being used at all, still we are seeing results like this:
You Linux image is way too big and you're probably seeing VM getting tired paging it in and out. Try reducing it to 384MB. You will also want to turn off timer ticks. I don't remember exactly what it is you need to echo to where in /proc, but I'm sure someone else does.
The other thing that's hurting you is KDE. Why are you running a desktop manager on your 390? Turn *off* X entirely--you don't have a local display there anyway. Again, I don't remember what runlevel "services, no X" (I think it's "2", but I won't swear to that) is in SuSE, but I'm sure someone does.
