This appears to be solaris only. I just tried a UDP mount & I see the
same problem. Is there anything else I can do?

The client and server here are both 450MHz machines. The server
and client are identical (450MHz PII (or PIII), etherexpress pro nics)
except that the server has 384MB of ram and the client has
64MB. The client was running a kernel from last week. My desktop
(196 MB 300MHZ PII) shows similar behaviour -- a drop from 7MB/s to
3MB/s. It is running a kernel from Monday.

Nice!
