[PHP-DEV] Method call overhead

Hi! I've measured the overhead for method calls in a variety of environments (Amazon, Travis, and 3v4l). The results are reliable and here's 3v4l . Some observations. First, as expected, direct calls are faster than static object calls, which are faster than object calls.
