I recently setup a web server on my machine. Someone told me that I should calculate saturation to see how good my server really is. Are there any scripts that let me calculate this?
If you are looking to load test, here is a huge list of tools. Some are free, some aren't.
BTW, if this is just a personal server on your desktop machine, I wouldn't even bother doing this. Unless you are using it on a production machine, it probably isn't worth the trouble. ;)
