See : ftp://fb0429.mathematik.th-darmstadt.de/pub/linux/okir/dontuse/ . Linux user-space NFS works very well. can anyone offer any examples of why they think a kernel-mode implementation would be significantly faster? by "very well", I offer this: the user-space NFS server can deliver 800-1000 KB/s. I got these numbers from a very mundane P5/133 running a fairly old v2.1 server on 2.0.28 with me using X on the console. the client was a P6/200 running 2.0.20 with a boring old SMC Ultra. this was with 8k nfs packets, and numbers varied from 780KB/s writing to 990 KB/s reading. using 4k packets reduces the numbers to around 700/850. media was a very polluted 10b2 net; I'll be able to offer you 100bT numbers in a coupla weeks ;) regards, mark hahn. -- operator may differ from spokesperson. hahn@neurocog.lrdc.pitt.edu http://neurocog.lrdc.pitt.edu/~hahn/
