I downgraded metacity, metacity and metacity-common to 2.16.3-0ubuntu2 from Edgy, but it's still slow. Perhaps there's certain rendering paths that are slow in xorg that metacity happens to use; all I know is that performance is excellent with kwin. Maybe I'll try some x11perf tests on my system and compare them against a Herd 4 LiveCD to see any differences.
Hmm,
