I run another set of benchmarks using x11perf.
I don't know how much they can help in pinpointing the issue(s), but they do show that `metacity --composite` is extremely slower than `metacity --no-composite` or `compiz`.

I'm attaching the output in LibreOffice Calc format, I think it's more readable that way.

An example line from the attached .ods file:
Test: 500x500 tiled rectangle (17x15 tile)
no WM: 772 (100 %)
metacity --no-composite: 699 (91%)
metacity --composite: 233 (30 %)
compiz: 688 (89 %)

The numbers are the repetitions, and inside the parentheses are the normalized values, with 100% being the highest.
The others are about 90% efficient, while `metacity --composite` is only 30% efficient, three times slower in that test.

I can also create a similar .ods for gtkperf, if anyone thinks that it will somehow help.
