I didn't take the time to control the configurations beyond
noting that they had the same amount of memory (32Mb, I think).
It would have been best to run it on the same hardware, but
it's not trivial to get hold of 4.1.x in my Sun neighborhood.
The one running SunOS 5.5 was actually diskless :-)  Both were
using UDP.

By "fast NFS write", do you mean the old kudp_fastsend path,
where the code built a monolithic UDP/IP packet in place and
bypassed the formal layering?  If so, SunOS 5.5 no longer
has that code, or any kind of equivalent.  It had to lose it
for transport independance and for NFS/TCP.

Thanks.

There was something fishy about the butler.  I think he was a Pisces,
