I'm having some severe problems with mounting an nfs filesystem and using it to store applications. From what I can tell, it works fine via TCP NFS, but unbelievably slow. When I don't specify TCP, and let it use UDP, it just breaks completely. For instance, when I'm running an application stored on the nfs server, I see this on the wire repeatedly, and the application never executes: galen.narnia.math.vt.edu -> calvin.narnia.math.vt.edu NFS C READ3 FH=DC3D at 0 for 8192 calvin.narnia.math.vt.edu -> galen.narnia.math.vt.edu NFS R READ3 OK (8192 bytes) calvin.narnia.math.vt.edu -> galen.narnia.math.vt.edu UDP continuation ID=60083 calvin.narnia.math.vt.edu -> galen.narnia.math.vt.edu UDP continuation ID=60083 calvin.narnia.math.vt.edu -> galen.narnia.math.vt.edu UDP continuation ID=60083 calvin.narnia.math.vt.edu -> galen.narnia.math.vt.edu UDP continuation ID=60083 calvin.narnia.math.vt.edu -> galen.narnia.math.vt.edu UDP continuation ID=60083 Each time this set of packets is seen, the filehandle is the same, yet it's reading 8192 bytes once every 10-15 seconds. This is a 100Mbit wire, so it should be loading almost instantly. Is there a possibility this is an ethernet card problem? Thanks for any help! -matt PS - please reply directly if possible - thanks -- Matthew C. Mead mmead@goof.com http://www.goof.com/~mmead/
