TCP is suposedly better for various reasons, but realistically I don't
think using TCP is going to help noticeably in a smallish LAN.
I'm not sure that sync has any effec on NFS on Linux on the client
side. However, specifying async on the server will help write
performance, at a potential cost in stability (see man exports for
details). I remember years ago a kernel patch for SunOS which enabled
async export, and it made a HUGE difference to PC-NFS clients. The
world has moved on a bit since that, of course :-)
Another thing to try is varying rsize and wsize on the client - that
can help performance too - default is 4096 - see if setting those to
8192 helps matters.
