I've been running YAF 1.94 for several months without any major problems, and the users are generally very happy with the forum and functionality. It's now getting to the time of year when loading on my forum increasing significantly, and performance issues start to become visible. What I'd like to know is whether there is a list of performance tips / config guidelines which should be followed to optimize YAF (e.g. cache settings, features switched off, db optimization)? If a list doesn't already exist, can anyone suggest what the key things to look at to optimize YAF performance are?

Thanks

Brian
