I've been pitting them up against the IBM and BEA jvms we have for the

"didn't fare too badly" = faster, slower, about the same? Any hard numbers?
I don't have any hard numbers, but things feel about the same or faster
than with a proprietary JVM. The thing to remember is that we have no gcj
optimizations turned on at this point. I know Bryce was working on it ...
Bryce, do you have a status of that?
My last eclipse -O2 attempt was a few weeks ago, and some fixes have
gone in to GCJ since then. At this point it should be possible to
compile most of the .jar's with -O2, but there are likely to still be
optimization bugs that cause eclipse to misbehave or crash when it is
built with -O2. Is resources.jar still used entirely uncompiled? We
should perhaps concentrate on that bug first.
Startup time is also an issue - we should be able to beat the JVM easily
here but currently we arn't. It would be worth profiling the startup
sequence to see if any obvious bottlenecks can be identified.
