I am looking for a simple tool or service to track the server-side performance of a website over time.It would be nice to have the possibility to register a set of URLs for different page types and see graphs how response/download time goes up or down over time.This might either be a tool to install on a server of our own, our a service. Of course, free of cost would be preferred, commercial solutions should be a lot cheaper than what I saw so far (50$/month is definitely far too much to spend for something like this)I know that the G-Webmaster tools offer a graph for average download time, but the problem lies in average. If a single page type is slowed down for some reason, it does not hit the average enough that the issue can be quickly detected.Thanks a lot for your suggestions,PeterEDIT: currently I am running linux servers, but I might be able to set up a windows machine for this, too. So software for both OSs would be interesting. (OS independency would be appreciated, though :)
Is there a good tool or service for tracking and analyzing website response/download time?

You could always do it manually. Just save the current time in your boostrap and then log the difference at the end of page output. From there, you'll be able to plot live graphs to visualize the performance of pages you're interested in.Or if you want an online service, here's a free one I just found called mon.itor.us. Offsite solutions like this will take network conditions into account as well.If you want a comparison with popular websites, this page lists the rendering times of a bunch of major sites. However, I find their figures a little suspect, since they display a lower time to load a full page on some sites than just to load the HTML.Along with that site, Pingdom also offers a paid uptime/response time monitoring service. Additionally, Pingdom has a free plan that only lets you monitor one site (I think they mean page) and have up to 20 sms alerts per month.
