Dear Martin,
Here are times of some various systems we have here. Two are alphas,
one running VMS at 300MHz, The other NT 4.0 SP3.
These times are from a format posted by Smith? earlier this year. I don't
think I got around to sending the times into him.
Alpha is a 500 Mhz Intel Pentium II, 266 Dual
Personal wokstation Processor NT 4.0

tt3 -- mean/geom : 0.405782 / 0.34502469 1.07070 / 0.64344983

As you can see the Alpha is very fast, especially being that we've had for
almost a year now. We are getting a 667Mhz system from Microway in a few
weeks. (I couldn't wait any longer for a 21264 system come out.)
I'll see how that compares. PS, The graphics seem slow, partly because
the card only supports 24bit/full color, plus I do not have the most optimized
drivers.
I'll try to run the test you list in your post.
BTW, there are a few Macs listed too.
