Re: Accessors in xs

After converting to XS, check your performance gains.

If they don't satisfy you, you might get another gain from converting some method calls to function calls since method lookups are significantly slower.

Yes, I've been thinking about that. I have a few more I want to convert first. I don't like going down to function calls if the rest of the program is OO, but I might not have a choice.

If you think your overhead is in method calls, check to see that you're not doing anything which invalidates the method cache: Assigning type globs Assigning functions into the symbol table Creating or removing named functions Modifying @ISA Since you're using XS already, you may want to write a short function to instrument PL_sub_generation to see if its changing. Anytime it increments, your cache is invalidated. New as of 5.9.4, this function is B::sub_generation	[reply]
