Features

Accuracy and details

Move mouse over elements to see additional data, like http-headers for each request, exact timing values, per host timing summary...

Site-Perf.com emulates true-to-life browser behavior in a smart and advanced way giving you all the values and figures which may matter to a speed-conscious site owner. See just how much value our detailed, accurate reports contain.

Keep-Alive supported

Site-Perf.com doesn't necessary create new connection for each request but reuses free previously established one, avoiding unnecessary delays which distort testing results.

Most measurement tools of today don't use Keep-Alive creating a separate TCP connection for every item to be downloaded. Modern browsers, on the other hand, use Keep-Alive to speed up site loading. Site-Perf.com gives you realistic results which reflect typical user experience.

Advanced on-the-fly HTML parsing

Site-Perf.com doesn't require html-document to be fully downloaded to extract urls of its requisites. It parses currently available data at delivery time.

Less sophisticated testing tools wait till the entire HTML page is loaded. When modern browsers start rendering the page as it is loading, such testing results are of little value. Get the true figures with Site-Perf.com processing the HTML in real time, in a highly optimized way so that simultaneous tests do not affect each other.

Smart parralel downloads

You can see how fast your site loads in various browsers by selecting proper value for 'max threads per host' setting.

Just like today's browsers, Site-Perf.com uses multiple download threads. The number of simultaneous connections per domain and per single test run is limited, which also imitates browsers behaviour.

Tests from around the world

Select various test-points and see how testing results are changed.

Find out exactly how fast your site is for visitors from all over the globe. See the bottlenecks and take measures to make your online business available to everyone. You can even test your ISP's network by using its server as the test point.

Full referer support

There's no need to make time-consuming changes to the way your site works to have it tested. Site-Perf.com will easily benchmark pages with active 'hotlink' protection.

Store and exchange test results

Your testing results are saved and can be seen at any time in the future from any location.

Just after Site-Perf.com has finished testing your site, you can view the performance chart, save the link to it for future reference, or send this link to anyone you want. This is a perfect way to keep your teem updated on latest performance figures.
