Brian -
There can be a lot of variables just under the designation "Alpha."
For example, we see:
DEC 3000 Model 300X 64 Mbyte OSF/1 3.0 15.7 s no load
DEC 3000 Model 300X 64 Mbyte OSF/1 3.2 14.3 s no load
DEC 3000 Model 400 64 Mbyte OVMS 6.1 21.2 s no laod
DEC 3000 Model 600 288 Mbyte OSF/1 3.0 9.5 s some server jobs
DEC 3000 Model 900 320 Mbyte OVMS 6.1 11.7 s no load
DEC 4000 Model 710 128 Mbyte OVMS 6.1 18.8 s some server jobs
all with IDL 3.6.1c. For what it's worth, there's a price range of > 3 there.
For what it's worth, with an unreleased beta version of IDL for the Power
Macintosh, we get:
PowerMac 8100/80 48 Mbyte System 7.5.1 20.9 s
Frankly, I think disk speed is a big factor in these, as the Power Mac figures
(test 23 = 7.38 s) shows in comparison to say, the 3000/600 running OSF/1
(test 23 = 0.82 s). The OpenVMS systems also have extra overhead in disk
writing (test 23 = 2.53 s on the 3000/900, 6.95 s on the 4000/710), but
you supposedly get a more reliable file system in return. In fairness, the
PowerMac disk I/O is still done in emulation.
Joe
P.S. Bet our PowerMac cost less than your Indy, though.... It certainly
cost about a factor of 3 less than the DEC 3000/400.
