How to measure Site Speed or Web Performance

A very hot topic last year: site speed, web performance, site performance or whatever you want to call it (got better suggestions?). But how do you measure the speed of you own site? There are several tool that can measure the load times of your site, but which one is right?

Google Website Optimizer Calculator

Ik vond vanmiddag toevallig een tooltje die ik ooit gemaakt had op basis van Google's eigen Website Optimizer Duurcalculator. Waarom had ik die tool gemaakt?
