Thats because each apache config is going to be different. I used to hate getting these sort of tickets from customers, asking us to optimize apache and mysql so their site would run faster.
The real issue is usually the site itself and its lack of optimization. If you are experiencing slow site performance run it through an analyzer like www.websiteoptimization.com/analyze/
. You can install some caching and change some of your directives in Apache but for the most part there isn't much "optimization" that is going to make your site magically start to run faster. MySQL does have quite a bit more that you can optimize based upon your queries.
I hope this info helps, if not be more specific on what you are wanting to "optimize" in Apache and why.
