Still, they are numbers. A 10x slowdown on that kind of code is normal for an interpreter (where 10x can range from 5x to 20x, depending on the semantics). But I think this is not a big issue: speed optimizations need to be possible, there's no need to implement them right now. lupus -- ----------------------------------------------------------------- lupus@debian.org debian/rules lupus@ximian.com Monkeys do it betterThread Previous | Thread Next
