By the way, I can't really quantify significantly, as it depends on what
kind of minit you have.  For a module such as the COM module, it can double
the amount of time it takes the script to run (if you load typelibs).  For
some other modules, it can be almost anything, if your minit is mostly
empty.  As a general rule, it's a bad thing, since it repeats things which
don't have to be repeated.

I thought you meant "significantly" worse run-time perfomance because
the engine can't optimize for function arguments, not because of what
kind of MINIT an extension has. We're still talking about standalone PHP
binary here.


Ah.  Well, YMMV.  If you have repeated calls to functions (not class methods, these are not optimized), it can be quite significant - you have an extra opcode that includes some stack manipulation, string duplication and strtolower of the function name, and slower pass_param opcodes.  I never actually benchmarked it, but it can be quite significant.
