very poor NFS performance from a beta3

[Jonathan Horne]

i updated my workstatino to beta3, and then got on a 6.2-p8 machine and 
mounted /usr/src and /usr/obj from the beta3.   tried to installkernel, but 
it moved as painful pace.  would get to the point where it moves kernel to 
kernel.old, and would just pause for a long time.  file transfer showed about 
104k.

i took this same 6.2-p8 box, and mounted src and obj from my main 6.2 build 
server, and reinstalled the 6.2-p8 kernel, and speed was as expected.

is there anywhere i can being looking to troubleshoot this problem (as to why 
the 7.0b3 would serve NFS so slowly)?
