[wp-hackers] Passing class methods by reference

[Jacob Santos]

I think the point is that both static method and functions are faster than
dynamic referencing of the method.

In truth, the benchmarks I've seen is not worth using one over the other
based on performance alone. Now I'm not quite sure what the issue is,
accessing variables is different from the overhead incurred with creating
the local scope of the method and function. That overhead is close enough to
not even matter.

There is a benchmark online between accessing globals, static class
properties, class properties, class constants, $this, self, etc. It might be
a look. However, 5.3 might have changed the speed somewhat. From what I can
remember, globals would be quickest, since $GLOBAL is a straight lookup
stored in the PHP space. Accessing any class requires accessing the class
memory space which will incur a bit of overhead.
