  That is pretty impressive. Also interesting that FF 3.5 seems to perform better than FF 3.6 according to those charts. Edit: Ah, nevermind, my mistake.

    Other way around - be sure to double-check the raw data at the bottom (3.6 is considerably faster than 3.5).

    You're looking at the IE 6 slice, not the FF 3.6 slice.

  I don't think this translates to the real world- one of the main things they did for that benchmark is add a special case for $('body') which will probably slow down (not noticeably though) most people's code.
  • jeresig 17y ago
    Erm - how would it slow down people's code? We're already doing a check to see if a tag name is being used and optimize based upon that, we just added one additional check to optimize for body. There is absolutely no way in which the check: if ( selector === "body" && !context ) ... Will have performance implications in your application.

      Please excuse my brevity- that is what I was trying to say with "(not noticeably)". Technically, or course it will slow down code not using the conditional.
