We recently migrated from NetWare 6.5 to a OES 2 running NCS on a VMware ESX 3.5 platform. The clustered NSS volume seems to have performance problems which is really noticable when saving Office 2007 documents.

The servers have a fibre channel SAN connection on the backend. Each VM is currently the only VM on their respective ESX host so there in no contention between VMs because there are no others running at this time.

Is there a tool for Linux and NetWare I can use to test IO performance. I still have other servers running NetWare connected to the same SAN I could compare to.
