Hello All! I have a small two-node cluster with AMD64 Opteron processors. It was running Centos 4 and NFS performance was good while not hindering performance. I replaced Centos with SLES 10 about 2 weeks ago and just now got around to really hitting it hard submitting jobs. Processes that normally took about 15 seconds such as normal IO (each processor writes its own data file) now require 10-15 minutes. When I observed the IO status, I saw that I could probably write the file by hand faster than the 2nd node was writing the files to the server. I would have to check but I think the mobo has integrated broadcom ethernet. I have tried the usual tweaks with respect to rsize and wsize and performance seemed to worsen if it changed at all. Has anyone experienced similar issues? And/Or does anyone have suggestions outside the wsize and rsize? Thanks! Tim -------------- next part -------------- A non-text attachment was scrubbed...
