I am very happy for reading this article, because I have some websites, that is too huge.. One of them have 6000 users, and they are in 1 table. In that table I have one index - in the id column. But I always do queries to the username-column! I see the problem by this, and maybe I should think about only using the ID, which I do on all of my new websites.. The problem is, that this website has more than 250 PHP-files containing these SQL-queries (and a lot of them), so I started out by indexing the username-column.. The website is on its own on a server with following specs: P4 2.8 GHz 2 GB ram 4 x 36 gb SCASI hd 15000 rpm 20/20 mbit internet connection. And with 80-120 online at the same time, there usually is a CPU load of 100%, caused by the mysql-nt.exe! Hope this changes ;) Thanks in advance..
