I have been testing NFS performance on some workstations, using a program to
write a 20-megabyte file with different-sized buffers.  The speed listed for
a Sparc1 when served by a Mips M/2000 is not a typo.  It really is that
slow.  Anybody have any idea why?

write speeds, in kilobytes/sec

blocksize:		8K	4K	2K	1K

server Mips M/2000:

DECstation 3100		310	135	135
Mips RS2030		310	140	140
Sun Sparc1		9	108	95	145

server Sun 4/280:

DECstation 3100		79	59	53	59
Mips RS2030		85	54	49	40
Sun Sparc1		82	67	62	62
