It certainly couldn't hurt to try running some different machine
architectures. My "64 bit server" machine is a tiny laptop running
Linux. Performance testing on some real servers might be interesting,
particularly for the 64-bit VM/32-bit image combination, which
would be used for Seaside servers and such.
You should be able to build 64-bit VMs for 32-bit image on those
machines without too much difficulty. For 64-bit images, it's
probably easiest if I send you a working image, because the original
64-bit image from squeakvm.org cannot be run on a current VM
(come to think of it, the procedure for working around that
gotcha would be worth documenting one of these days).
In addition to updating the plugins, there are probably lots of
issues and bugs that will show up in the 64-bit image if you run
some of the SUnit tests. I'm not sure if any of these are worth
working on at this point, but identifying some of the problem
areas might be helpful. I suspect that a large proportion of
things that appear broken in the tests will turn out to be
problems in the tests themselves, but getting that right is just
as important as fixing any problems in the image per se.
At some point we should try to convince Tim to copy his archive
of VMMaker-tpr.00.mcz through VMMaker-tpr.nn.mcz over to SqueakSource
before he gets run over by a truck and the change history is lost
to the ages.
