	"You cannot get more than 600KB per second out of the

This doesn't sound right.  I just tried sequential disk reads from a
large file on a Tektronix XD88 (88k-based) workstation and got
650KB/sec.  Even our wimpy 68020-based systems get 450KB/sec.  This
through a slow SCSI channel, and the file system is Berkeley FFS.
