The first test is faster (Azure ~35 FPS, no Azure ~15 FPS).
Tests 4 and 5 are slower with Azure enabled. Unfortunately the test doesn't list separate results for each test. Could someone modify the test to separate the results?

4: Azure 5 FPS No Azure 11 FPS
5: Azure 3 FPS No Azure 7 FPS

The test is slideshow-like whether Azure is enabled or not.

Azure:
Benchmark Score: 497
Average FPS: 11

No Azure:
Benchmark Score: 429
Average FPS: 9

There's two reasons, one of them is shadow drawing which needs to be optimized a little. The second is we're also needlessly drawing shadows in some cases. I've got a patch to fix the latter which I need to clean up a bit.

I thought some more data might be useful.

Running the benchmark on Mozilla/5.0 (Windows NT 6.1; WOW64; rv:8.0a1) Gecko/20110728 Firefox/8.0a1 (so I think with Azure turned ON)

Tests 1, 2, 4, 5, 6 - are drawn correctly
Test 3 - some asteroids have white shadow, the screenshot: http://img718.imageshack.us/img718/8721/watchthewhiteshadow.png

Test 1 runs very fast, sometimes it slows a bit, but not for much and not for long. 100-111fps
Test 2 runs pretty fast, sometimes it slows a bit, but not for much and not for long. 71-67fps
Test 3 runs very slow. 8-9fps
Test 4 runs very slow. Starts with 21-22fps, but then drops to the constant 14fps.
Test 5 runs very very slow. Starts with 12fps, but then drops to the constant 5fps.
Test 6 runs pretty fast. Starts with 111fps, but every time asteroids explode and numbers appear - it falls down to 37fps, after every explosion it gets restored to 71fps (not 111fps as at the beginning).

How does this look in the current Firefox Nightly?
