  • Waits for and records when the indicated DOM element becomes available on the page. The DOM element is identified in attribute=value format where "attribute" is the attribute to match on (id, className, name, innerText, etc.) and "value" is the value of that attribute (case sensitive). For example, on SNS pages name=loginId would be the DOM element for the Screen Name entry field.

    There are 3 special attributes that will match on a HTTP request: RequestEnd, RequestStart and RequestTTFB will mark the End, Start or TTFB of the first request that contains the given value in the url. i.e. RequestTTFB=favicon.ico will mark the first byte time of the favicon.ico request.

What is Website Performance Tester?

This tool provides feedback on how quickly your website loads. It will grade certain aspects of your webpage, and give suggestions on what can be improved. Here are some features of the utility:

  • Loads your page with an actual browser, so you know what aspects are slowing your site down in certain browsers.
  • Shows the time it takes each file (CSS, JS, images) to load and render.
  • Provides full headers for each file requested
  • Checks browser configuration for settings such as keep-alive, caching, and gzip compression
  • Checks that images are full compressed, progressive, and optimized
