For those of you having problems with CPU usage going through the roof on your application server boxes, I have the perfect solution that will definitely get rid of those pesky 99% - 100% CPU usage rates: make your database server's disk I/O really, really slow. I guarantee everything will be A-OK. Nobody will be able to use more than, oh, 15% of CPU! If they can, they're definitely breaking the rules and you'll need to slow that codepath down manually.
