The common case is where setTimeout() is called with two arguments, the callback and the timeout. Specifying optional arguments in the parameter list forces common case calls to go through an arguments adaptor stack frame. PR-URL: nodejs#1221 Reviewed-By: Trevor Norris <[email protected]>

LGTM Aside: Thought the penalization was mostly fixed (so that the performance difference was essentially white noise) in V8 for calling a function with too many parameters. My bad for not catching that before it was pushed. |
