The following figures were obtained on a CDC Wren IV, embedded SCSI, 300
meg drive attached to a 2090. The drive was empty at the time. Further tests
with the drive about 70% full and in use showed a dropoff in the 32K buf
read speed to about 650K/sec.

.File create/delete:	create 16 files/sec, delete 52 files/sec
.Directory scan:		102 entries/sec
.Seek/read test:		125 seek/reads per second
.r/w speed:		buf 512 bytes, rd 87381 byte/sec, wr 29454 byte/sec
.r/w speed:		buf 4096 bytes, rd 291271 byte/sec, wr 187245 byte/sec
.r/w speed:		buf 8192 bytes, rd 436906 byte/sec, wr 262144 byte/sec
.r/w speed:		buf 32768 bytes, rd 873813 byte/sec, wr 374491 byte/sec

If all the MSDos machines were laid end to end,
