I was doing my obessive-compulsive reloading of Digg’s main page, and came accross this article on load testing with open source tools. Good read.

It’s a new year, and time for resolutions and all that. In that spirit, I’ve put together a list of 4 things you can do to improve your load balancing infrastructure. Some are quick, some are more involved, but they’ll all pay huge dividends.
Number 1: Get Your Sniffing In Order

Diagnostic tools are critically important. It’s something that often gets forgotten in product development, but it can make or break a product, especially in a product’s formative years (or during big code updates) while the kinks are being worked out.
The swiss army knife of diagnostic tools, and the one most essential in the entire networking [...]
One of the most common problems that afflict load balancing situations is the “same subnet” problem. This is when a client tries to browse a Virtual Service/VIP from the same subnet as the real servers. Lately, I’ve seen this come up on the mailing list. See here (and my response) [...]
