Hello!

I'm seeing my PPro200 with FreeBSD 2.2.7-STABLE being about 3 times slower
(according to iozone) then Irix 5.3 running on R4000 at 100MHz with SGI's
latest NFS3 patches. Memory is plentyfull.

The client is also an Irix machine very similar to the server. The network
is 10BaseT and the numbers are (24Mb test file):

	Irix to FreeBSD:

        237929 bytes/second for writing the file
	5642561 bytes/second for reading the file

	Irix to Irix:

	717997 bytes/second for writing the file
	5423668 bytes/second for reading the file

I do not really trust the "reading" numbers, because they seem to
represent the cache performance. The mount options in both cases
are:
	3,rw,intr,bg,hard,private

changing "hard" to "soft" did not affect much. Removal of "private"
slowed things down to

	NFS Irix to FreeBSD:

        162653 bytes/second for writing the file
	5094296 bytes/second for reading the file

	NFS Irix to Irix:

	591997 bytes/second for writing the file
	5221125 bytes/second for reading the file

The FreeBSD machine has DEC's PCI network card (in 10BaseT mode),
the machine is not slow at all and local disk access is

	FreeBSD local disk access:

	4575604 bytes/second for writing the file

Straight:

	FTP get Irix to FreeBSD:

	112469104 bytes received in 102.27 seconds, 1073.94 K/s

	FTP put Irix to Irix:

	112469104 bytes sent in 136.38 seconds (805.33 Kbytes/s)

The machines are on the hub with about 8 other mostly idle machines.

Any clues as to how to tune the FreeBSD NFS up are greatly appreciated!

Thanks!
