We recently migrated from a 7 year old file server running on a single proc dec alpha running Tru64 and utilizing Truclustering for HA, to a Redhat cluster suite and gfs for HA on a dual duo core dell 2950 with 32gb ram, and have been having major performance issues. Both have fiber attached storage. The old file server grossly outperforms the new one! The way we are utilizing it is for nfs file serving only to multiple clients. It doesn't take many users doing much on the clients, to easily drive the load on the boxes into the 10+ range, where on the old file server it never got above 2 or 3 to perform the same tasks. The load and performance was much worse, but improved to where we are now after setting all of the volumes to statfs_fast 1. I also set nfs threads to 256, which helped some, but I don't know what more to do, and we are at the point of abandoning this platform if we cannot get it to perform reasonably. Please help!
