Sorry - I meant compared to straight functions.  The context (in my head) was

$object_i_can_use = My_Class::instance();
vs.
$object_i_can_use() = my_class_instance();

Where the former stores the as a static property or variable, and the
later accesses a previously created global.

I didn't actually benchmark that specific scenario, though, so I
probably shouldn't even have mentioned it :)
