It doesn't, it just uses --replace. There is a built in delay for the
decorator, set to 5 seconds by default. Can you try configuring this
to, say, 1 second and see if this is what you are seeing?

I still need answers to the first questions too:

1. Is it consistently slow
2. When using verbose, is there a specific test that's slow?
3. Is it slower at the first run, or also slow after it has saved the
results of the test too?

Compiz-manager only runs tests once in a normal setup, which would
make it considerably FASTER than pretty much anything that doesn't, so
I need to know the answers to these questions to determine the reason
for the slowness.

I would also very much like to get confirmations from others.
