Some people got it seriously, some people were complaining about the original test saying that the TaskSpeed util is not really representative case affected by css-selecters and stuff.
So I sat down and had written my own simple test, you can get it over here. This test eliminates any unnecessary disturbances, like elements selection, gets the questionable elements building process to the minimum and creates clean, pure functionality one-on-one performance test results.
The result is predictable and actually correlates pretty closely with the original TaskSpeed based benchmarks.
As you can see, in a blunt, face to face performance test, RightJS does murk jQuery several times.
Get use to it.
UPD: As I'm working on the test suite, I've added the pure-dom test and also publishing results for Opera.
