I'd have to take back my educated guess and go with BrowserUk. I tried this on Solaris and Linux using several different variations and the substr version always comes out over 40% slower. And I did not see the push being twice as slow as the explicit array assignments on either system.

Besides platform, the data being operated on would be the only other factor I can think of that might make the original so much different from what others have tried.
