Hello,
JFYI, Sun shipped the next major Java release:
http://java.sun.com/javase/6/.
yes, and I got an amazing 40% speed improvement on winxp emulated inside
parallels on macosx over java5 on the application I'm currently working
on (some in-memory RDF manipulation library).... so much that it's
faster to run java6 on winxp emulated than it is to run it on macosx's
java5 (haven't tested harmony there yet, I'm waiting for the blessed
snapshots).
That's because winxp isn't being emulated. It's running directly on
that lovely little CoreDuo processor in your Mac :)
This seems to be consistent with my previous benchmarks on linux: Sun's
java6 is perceptually faster than Sun's java5.
Yes. As I understand it, Sun stopped most major perf work on Java 5 a
long time ago to focus on Java 6. I've been told that some improvements
for 6 were put in the last updates to 5, but clearly not everything.
Here's some other info :
