Re: JamVM 1.2.5 released

[Robert Lougher]

Hi,

Robert Schuster has sent me some very interesting performance results
with JamVM.  I don't know if he wants them made public, but on the
fosdemo, JamVM 1.2.5 performs almost as well as Sun's Hotspot or IBM's
VM (within ~0.5%).  Admittedly I think it's spending most of it's time
calling native code via JNI, but it's interesting none the less.

If anybody else sees any dramatic speed improvements with 1.2.5 I'd be
very grateful if you could provide feedback (equally, if you _don't_
see any improvements).  It's not just an ego-trip -- feedback will
help me tune the VM and suggest future optimisations.  I only have a
limited number of architectures and some defaults are pure guess-work.
 It's also nice to get positive feedback once in a while, instead of
the usual bug reports :)

Thanks,

Rob.
