Techs !! Sorry for the late summary. A lot of replies but somehow it did not help. I am still waiting for oasis in the desert... Maybe some more replies will help... Thanks Awaneesh Original Post: - I have a system perfornace issue on a E450 box with 2 cpus and 1gb ram. The system eats up around 66% kernel resources. Responses: - andy.lee@orange.co.uk Some thoughts : You are using disksuite , are you using raid5 or mirror ? Is it only the rootdisk that is mirrored , are you using the same version/partitions disk suited on your 'equiv' test box. (Raid5 can really suck kernel cpu) Have you got the latest disksuite patches installed ? I suspect it is down to disksuite. You could try mounting the partition directly outside of disksuite control to check . You seem to have high writes to md0 is your app swapping a lot ? Trevor Paquette Off the top of my head I am seeing ALOT of disk io to some sort of meta device. You may want to off load all that disk io to an actual REAL raid array, and not use SDS. gez@beenz.com Your md30 / 31 /32 seem to be a little high on the svc_t is the Application only writing to these disks and are there metadbs on them ? Can the load / metadbs be distributed. Bertrand_Hutin look at the results of sar -g pgscan/s should remains >390 Hindley Nick Its a bit difficult to tell but you seem to have a lot of I/O on md10 and from there onto c0t0d0. Do you have a lot of errors being churned out into a log file somewhere? __________________________________________________ Do You Yahoo!? NEW from Yahoo!
