So I probably shouldn't respond to this because being on the Chrome team no matter what I say it will sound defensive but:
*) Are you sure they are computing the same things? For example mjs doesn't appear to have a true matrix inverse so you're comparing apples to oranges vs the other libraries there.
*) I added the math library from the tdl stuff. They are slightly faster at some things and slower at others. Attached (sorry, new to git)
*) Matrix math isn't everything. For example running the webgl aquarium on FF4b11 vs Chromium 11.0.668.0 (74525) on your hardware (I have the same machine) using this url
At 50 fish
At 1000 fish
Of course none of that explains why FF is 5 times faster for your test as it is.

See the data below ...
d the benchmarks Brandon Jones created in his glmatrix library: https://glmatrix.googlecode.com/hg/
My changes include:
- I'm only including the benchmarks.
- I've updated to the latest mjs as of Dec 15: 16:8e5b0944ef1e and included it in several more tests.
[The somewhat lame reason this is a fork is that it was taking me longer thanI wanted using mercurial (don't use hg much) to follow the typical workflow I use on github, fork a repo, push my changes into a branch and send a pull request to the original developer ...]
