Hi there, as I suspected NFS to be a brake in performance, I looked around for information on how to tune NFS.
In nfsstat, I realized that 75% of all requests concerned file attributes. I also experienced system wide delays simultaneous with requests for direcory contents. Although I can't verify that NFS and not the NIC is the problem here, I learned about two further options to tune NFS: i) async: allow nfs to answer requests from cache (before committing) this was common until 1.0, but might lead to data loss if power is suddenly turned off. ii) increase amounts of nfsd threads from 8 to ? Are there any experiences on the list with this? At the moment, our TX150 tjener runs 1 LTSP (+ 14 thin clients), 1 Linux work station, 20 WinNT and 4 Win2k work stations. Regards Ralf
