Sometimes speed is a great indicator of input validation that is or is not being done. If it blows the doors off firefox and IE it may not be doing everything as tightly as it should be.

Jason, good point. I know timeouts are set at varying levels to allow for correct functionality (i.e. page rendering).

With regards to DOS attack prevention, a simple alert bomb will still cause havoc on a heavily utilised winbox, so fancy timeouts do nothing in these cases… bring the fast JS parsing and execution I say :)

Being the fastest may not be a good thing…..

You probably don’t want give some old web page the ability to max out your CPU usage. Browsers intentionally run JavaScript at slower speeds to prevent some types of DOS attacks.
