There is essentially no per machine optimization. The VM is written in
Smalltalk however it does need a certain amount of C to bootstrap it.
This C is generated by Smalltalk in a running VM and is the same for all
platforms. The last big change I remember was to make it bug compatible
More details here:
The real difference is probably in whatever C compiler that a given VM
maintainer is using. If it's VC++ on windog vs. gcc on Irix then that
will explain the difference to my satisfaction.
Live like you will never die, love like you've never been hurt, dance
like no-one is watching.
