I agree. Have you read the FAQs about NFS server with Sun clients?
You may want to carefully specify NFS v2, for both clients and servers,
at least on the client -> FreeBSD server link. To be fair, you should
use whichever protocol version is fastest with the Solaris server,
probably V3. If your client is SunOS older than 4.1.4, you probably
don't have V3 support.
By the way, I expect a Solaris server running on SMP hardware to out-
perform a FreeBSD server; their threaded NFS server is quite fast.
For the difference in price for the hardware, FreeBSD certainly provides
acceptable performance. ;^)
