[computer-go] Language War!

[Jim O'Flaherty, Jr.]

Peter,

I have a similar impression about size, although I cannot verify it right this second.

Given where you are, have you checked Javolution?
http://javolution.org/

This guy is a Java performance/memory footprint nut-case.  If you look at his posting on http://www.javalobby.org, you will see he stays right on top of performance and footprint metrics around the core collection class replacements he has developed.

Given your framework is suitably designed, it might take you a very small window of time to try out some of his "replacements" and see what kind of improvements you experience, aasuming you have some baselines against which to measure the resulting differences.


Jim

I don't know what specific performance problems you're having in Java

obviously performs much better, but only few. And fundamentally your
program can look very similar. Still, coming from Java I predict
moving to C++ will prove to be very frustrating. But it's your call.


One of my big bottlenecks is memory space.  I get the impression that a Java object is much larger than a C/C++ struct containing the same information.
