In this guide I will explain best practise regarding performance in MySQL, PHP and of course our loved Yii Framework. Since this is a complex topic, I will start with some basics and then expand this guide from time to time. Since this wiki can become big, you may click on View history - there you can see what changes have been made, so you don't miss anything.
Installing WAMP on XP was pretty easy; W7 is not so trivial. It's not difficult once you know, but it took me best part of a day to figure out and required gleaning various bits of information from around the web; this tutorial brings it all together in one place to (hopefully) make other peoples lives that bit easier. It does assume that you are reasonably happy configuring Apache, PHP, and MySQL and mainly deals with the W7 quirks.
