That's a pretty vast question... I built my first CWP server and muddled around with the configs for roughly 2 weeks until I got things to a workable, satisfied state. It actually wasn't too bad because my years of cPanel experienced gave me a good reference point. Then I was able to build 2 more CWP servers in a matter of a few hours once that initial learning curve had been done. And then I was able to shuffle some accounts back & forth between them to better load balance and take advantage of more resources on one server.
