FreeBSD has outperformed linux by several orders of magnitude in client side NFS for a long time. The newer linux development kernels come close, but when concurrent NFS requests are made Linux chokes while FreeBSD maintains a broadband'ish state. I know i posted several times about problems with NFS (about a month ago) but since McKusik's fixes I've yet to have a problem. In so far as serving NFS... the Linux userland NFS server is hardly a match to the FreeBSD kernel impelementation. Stability is another matter and I haven't seen enough to say anything conclusive for either side. Both implementations suffer from lack of support for files > 2gb in client side requests which should be addressed, somehow/somewhen. A recent Linux article suggests that Linux NFS will bipass the "mbuf" layer, ie. the NFS code will directly reassemble packets into RPC requests thereby saving _one_ copy of memory. This is really neat, but then makes NFS dependant on the protocols which it is supposed to be independant of. Btw, Mike Smith's new ACCESS caching seems quite stable and i was wondering if it had been commited. -Alfred To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
