I compiled diskperf.c and ran it on two different sun 386i workstations.
I made no modifications to the benchmark and ran it on a stock version of
SunOS 4.0.0

					sun 386i (model 150/8x)
File creations           (files/sec)	18
File deletions           (files/sec)	54
Directory scan         (entries/sec)	976
Seek+read            (seek+read/sec)	1976
Read speed,    512 buffer (byte/sec)	776722
Read speed,   4096 buffer (byte/sec)	2995931
Read speed,   8192 buffer (byte/sec)	3534525
Read speed,  32768 buffer (byte/sec)	3700856
Write speed,   512 buffer (byte/sec)	280618
Write speed,  4096 buffer (byte/sec)	1728421
Write speed,  8192 buffer (byte/sec)	2069557
Write speed, 32768 buffer (byte/sec)	1787345

Notes:
	(1)	Sun-386i model 150/8x uses a 20MHz 80386, has 8 MB of memory,
		and 32KB of cache.
	(2)	Sun 386i configured with a CDC Wren IV (94171-300) disk
	(3)	Sun 386i uses the Intel 82380 DMA Controller
	(4)	Sun 386i uses the Western Digital 33c93 SCSI Controller IC
