First eliminate network problems as a possibility by using netperf in both directions to get a baseline. Doesn't Linux mount ext2 filesystems using async writes by default? Isn't that dangerous in general, and worse with NFS? Check the mount options for the host file system on the Linux NFS server.

FreeBSD client to Linux server, I get really good writes. Linux client to FreeBSD server I get about 4x slower writes. 2.37 sec for a 16MB cp qtrial99.exe test.exe vs. 10.21 sec for the same (~16MB file) done via 100Mbit FDX switch with 595 on the Linux box, fxp on the FreeBSD box. wsize&rsize set to 8K, vers=3, proto=udp,nolock (seems to be the fastest) ftp's look pretty close to the same. Where do I go from here to debug the issue? Unfortunately, I don't have any other UNIX boxen on the network to verify where the problem is.
