I have 3 file servers which seem to be running slowly - although on the console they are super responsive. I've been through everything i can think off to try and diagnose the faults to no avail.
Two of the servers are not that old (about 2 years) HP DL380 G5 Dual Quad Xeons with 6gb ram.
The Third is HP Dl380 G4 Dual Dual Xeon with 4GB Ram. But i don't think its a hardware problem (enless switching)
First of all i removed the HP network teams which i had recently implemented to try and speed access up and thought as this had changed it could have been this - not this.
Also checked the switch for any packet errors - nothing.
i've been through the raid diagnostics and can't see anything wrong. I've checked the scheduled defrag was running (schduled for each sunday) yep all working.
Also checked there doesn't seem to be that many users active during the periods of slowness (around 100). The Pages/Second tends to sit during heavy loads averaging around 6/700 pages/s but sometimes is maxing at 5500.
I've just disabled FSRM quotas to check that its not that being slow when files are being written to the disk.
Its not our AV as its on access scanning is disabled and is scheduled to run at 5pm to check for virus's and all client machines scan the files anyway.
Any other ideas for me to check before i go throw these servers out the window? I'm thinking it could be a strange config as our predecessors seem to have done some strange things on other servers.
