I've heard (sorry don't remember source but it was found via google) you should limit yourself on linux to max 8 nfsd's per processor, that would mean 32 processes for 600+ mounts. Yikes. We have about 15 mounts per server process, 8 processes per processor, also gives poor yield. We're migrating to a SAN with GFS to "solve" this issue (among several other issues). Is your server's network card stable and not saturated? > 3) will change mount options, remove bg, add noac,rsize=32768, wsize=32768 32768? Do you have the networking equipment to handle that without fragmenting? Are you already using jumbo frames with your 8192 packet size? Good luck, Dan W.
