All: Anyone having any good fortune with performance of NFS shares in a current 5-STABLE against Windows 2003 Services For Unix 3.5 server? I'm able to, with some pretty extreme tuning, get as much as 1MB/sec out of a 100Mbps link, but I'm able to FTP to and from the same host at 8-10MB/sec. I've tried different send/receive windows, NFSv2, NFSv3, forcing TCP/UDP, and setting the tcp windows to some pretty outrageous sizes. None of the above really seems to net me performance above 500-600kB/sec (testing via rsync --progress -av / local/dir /mnt/nfsshare). mount_smbfs is also incapable of going beyond 1MB/sec in a similar arrangement. Why on earth is performance sucking so bad? Thanks, -t
