Tuning NFS on OS X

[sawyl]

After my problems with NFS last week, I've applied a few tunings. Essentially, the changes involved switching the transport from UDP to TCP and upping the buffer sizes. This roughly doubled the read performance and put an extra MB a second onto the write performance.

Once I'd got the options right, I simply made them the default in the usual OS X way:

1. Changed the entries in /etc/fstab
2. Updated the netinfo data with sudo niload fstab . < /etc/fstab
3. Checked the change with nidump fstab .

And now, when I mount up the file system, it automatically comes up with the right options.
