Message-ID: <3212@ucbvax.ARPA> Date: Mon, 12-Nov-84 15:45:22 EST Article-I.D.: ucbvax.3212 Posted: Mon Nov 12 15:45:22 1984 Date-Received: Tue, 13-Nov-84 06:44:30 EST Sender: daemon@ucbvax.ARPA Organization: University of California at Berkeley Lines: 19 From: Bill Mitchell Has *anyone* done *any* disclosable benchmarks on the 8600? DEC's been talking about the machine for who knows how long and now that it's "here", the sum of the performance data that we can get out of them is "up to 4.2x a 780". Does anyone know what the low end of the scale is? Is the 4.2x figure for real time or is it for CPU-bound activities? I'm assuming that 4.2x is some sort of reasonable upper bound on throughput, but what's the lower bound? On an unrelated topic, why is DEC pushing their UNIBUS disks so hard? Sure, they've got the slide shows and the answers about how there's plenty of room on the UNIBUS for the disks, but we've had no luck in pinning them down about why all the emphasis is on the UNIBUS disks and why the MASSBUS disks are hardly mentioned. I've heard that DEC is overstocked and is trying to reduce the surplus; anybody know if there's truth in this? Bill Mitchell
