This is a nice trick to know about. Especially since splice is quite slow. :o

The indenting is a bit off here.

Wait until you see the numbers for EventEmitter#removeListener(). :-) |

@chrisdickinson Fixed the indentation and renamed the function to spliceOne(). PTAL. |

Rename the url.parse() benchmark from url.js to url-parse.js. A follow-up commit is going to add another one for url.resolve(). PR-URL: nodejs#184 Reviewed-By: Chris Dickinson <[email protected]>
Replace the call to Array#splice() with a faster open-coded version that creates less garbage. Add a new benchmark to prove it. With the change applied, it scores about 5% higher and that is nothing to sneeze at. PR-URL: nodejs#184 Reviewed-By: Chris Dickinson <[email protected]>
