I use rsize=4096,wsize=4096 when I mount nfs from one NetBSD to
another.  This made things more than 8x faster from the default.  I
don't know why.  I suspect there is too much burst traffic for the
crappy ISA ethernet card I have to buffer it.

When using TCP, btw, I notice a severe dip in performance, using a
ping-ping read/write loop, around 4096 byte read/writes.  I get almost
7.9Mbps at large buffer writes, abour 3.2 around 2048, but at 4086 it
drops to < 1Mbps.  At 8192, it doubles, and 16384 it starts to get
back to where it should be.

Just for kicks, 4096 is the page size on the i386.  Is this a factor
perhaps?  If not, well, anyone wanna guess what is going on?  :)

Yea, that's a BIOS problem.  I don't think the BIOS can report more
than 64M.
