Hello,
I am using an p520 with Virtual IO Server 1.2, testing Suse Server 9 within one partition. I just installed it, no services are being used, Linux top says it is 100% idle, but the IBM partition manger (IVM) says it is about 10-20% busy. If I use an idle AIX 5.3-03 within an partition, this uses just 0-1% CPU.
No idea so far, I´d have to ask IBM about there software. May be just a reporting problem.
Another problem I found is disk performance, I use dd from the RAW device to /dev/null with a 1024k blocksitz, with Linux gets about 50MB per second, using the same disk with an AIX partition this gives me about 85MB/sec.
Mmh. did you try different blocksizes, esp. 4k would be of interest? What does 'hdparm -tT' report on the raw device? Bye, Jack. -- Joachim Plack, tel suse@461, mail jplack@suse.de SLES on POWER = SATISFACTION GUARANTEED We'll send you another copy if it fails.
