I'm stil looking into how I can get reasonable performance from ia64 to
ia32 linux, with regards to maximum server block size of 8K. I found some
references to 64K blksize limit with V3 (I assume this meant what the
protocol definition will support - not what linux will support), and also
a 32K blocksize for TCP mounts.

http://www.linux.org/docs/ldp/howto/NFS-HOWTO/performance.html

I haven't played much with TCP mounts, how stable and how well do
they perform under linux?

I'm currently getting my ia64 box rebuilt in order to an NFSSVC_MAXBLKSIZE
of 64K. Anyone ever tried it?

Cheers, Mark.
