Slow is an understatement. My 486/66 was about an order of magnitude
faster than the native Compaq JVM on my 500Mhz Alpha Miata. I
understand that with a decent JIT the same box could run as fast as a

Naw, it runs out of the box, no need for Linux.

Wow, I'm surprised. Our application which is *way* bigger than the
Volano stuff didn't use nearly that much memory. However, it was so
slow that maybe it was because I never really pushed it hard, and
did simple verification tests with it.

I had everything running on the Alpha that was originally provided to
the FreeBSD/Java team for doing the Java port, but due to lack of
interest the box sat completely idle for years and has since been put
out to pasture.
BTW, thanks got to Andrew Gallatin who helped make the Linuxulator
changes so that it would work, albeit slowly.
Contacts at DEC/Compaq were met with interest, but there was little
techical help forthcoming.
IMO, the Alpha platform is dead as far as Java is concerned. It's a
great architecture, but it's really not worth throwing resources toward
something that will never outperform a PC that you can buy for $300 new.
