Old Vector and Matrix constructor functions would create all methods and make assignments with each call. A lot of speed-ups can be made by using shared properties through the prototype chain. Since methods and initialized properties are shared among all instances they're only created once. Some tests can be seen at examples/performance-test.html Some results: Chrome //6.4 times faster performance-test.html:25 Vector2 x 5000000: 213ms performance-test.html:30 Vector2Orig x 5000000: 1366ms //8.3 times faster performance-test.html:37 Vector3 x 5000000: 241ms performance-test.html:42 Vector3Orig x 5000000: 2015ms //3.8 times faster performance-test.html:49 Vector4 x 5000000: 278ms performance-test.html:54 Vector4Orig x 5000000: 1059ms //7.5 times faster performance-test.html:61 Matrix4 x 5000000: 937ms performance-test.html:66 Matrix4Orig x 5000000: 7004ms Firefox //6.8 times faster Vector2 x 50000: 45ms Vector2Orig x 50000: 307ms //11.5 times faster Vector3 x 50000: 48ms Vector3Orig x 50000: 550ms //3.8 times faster Vector4 x 50000: 61ms Vector4Orig x 50000: 234ms //9.4 times faster Matrix4 x 50000: 199ms Matrix4Orig x 50000: 1878ms where "Orig" are old versions of the objects. Running these tests multiple times can yeild different results due to browser cache. However the results are always kind of similar in terms of speedup.

- Seems like new dev version of Blender has some Python API changes. (Can't wait until Blender 2.5 gets released :D)
