regular expressins performance

I'm creating a new program. The ONLY thing which is important for me is the running time of the program. Should I use a regular expressions, or maybe should I write my own search code?

Just leave your main() function empty. It can't get any faster than that. Seriously, what are you trying to search for and in what?

You should use the faster approach. :-D Seriously it may depend on a some factors like the complexity of your regex queries and the efficiency of your own search code (standard regex code is usually quite fast) :)
