Web performance testing tools are mainly divided into three kinds, one is to test page resource loading speed, one is to test page loading finished page rendering, JS operation speed, there is a general analysis of the page evaluation, the following respectively, these tools are described, if who has better tools also please share under.
Firebug
:Firebug is the most classic Firefox development tool, can monitor the request header, response header, display resources load Waterfall diagram:
HttpWatch
:
HttpWatch function is similar to firebug, can monitor request header, response header, display resource load Waterfall diagram. But HttpWatch can also display gzip compression information, DNS queries, TCP link information, personal in monitoring HTTP requests compared to using httpwatch,httpwatch including IE and Firefox plugins. However, the HttpWatch Professional version is charged, the free version has some feature limitations.
DynaTrace ' s Ajax Edition：
DynaTrace is I often use 1 free tools, the tool can not only detect the resource load waterfall diagram, but also can monitor the page rendering time, CPU costs, JS analysis and execution time, CSS parsing time and so on.
Speed Tracer:speed Trace is Google Chrome's 1 plug-in, speed trace advantage Point is used to monitor the resolution of JS execution time, but also can monitor the page redraw, reflux, this is very strong (Dynatrace can also have this function).
