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
