There isn't nearly enough information in your post to make a good assessment. What services are you running? Are you using any Apache specific functionality? Are you using an Apache module like mod_php, mod_python, etc, to host a webapp? Do you need to serve more than one type of language through a single httpd server. E.g., a PHP app and a Rails app? There is no one-size-fits-all web server. It's all dependent upon your specific needs.
