Hi!

I'm looking for details on how v8's regular expression optimizations work 
under the covers, and if there might be something to improve the 
performance of a given regular expressions first execution. From what it 
looks like trying some things out, v8 does most of it's optimizations after 
a call that uses the RegExp and not when the constructor is called (eg. 
through `new RegExp()`).

I am Wondering what some options are in this area to move around the cost 
of compiling/running the regular expression.

Thanks in advance!

Joel
