An interesting talk goven at the USENIX conference by some folks from Convex(Tm), spoke of their rather large block sizes on their disks(I think it was 16k/block). This was one of the ways that they were dealing with speed issues. I can't do this since I don't have source fot SUN O/S. I can only speak for some of my customers who've I done consulting for; I yanked the 451's and installed the Interphase controllers and some of these newer , much faster drives. Their performances have rised much more than I could have envisioned; load times for some Lips transactions went from 25+ minutes to 7-10 minutes. It's al relative to the speed of DARK......
