Response time tracking

Hi,

I love the "uptime" feature for tracking any downtime. However, another feature I've had with other site monitors is a "response time" metric. This shows how long the page took to load, and stores it. Looking at reports, you can see if changes you made (or your hosting company made) have slowed the site load time. So it's more than just "Is the site up / down", but allows you to review "How fast" has my site been loading. Would be a very handy addition on the "Uptime" reporting area.
