If you are measuring wallclock time, I don't see how the overall
slowdown is a reliable measure of any code performance. The test
suite includes quite a few tests that deliberately wait for some
seconds for various reasons, and those times aren't affected by the
byte code or the interpreter.
We need to measure CPU time.
