High-performance web development: Web performance testing tools recommended Source: Network reprinted time: Font: [large, medium, small] favorites I want to contribute to share on Weibo
Web performance testing tools are mainly divided into three types: one is to test the loading speed of page resources, the other is to test the page rendering and JS operation speed after the page is loaded, there is also a general evaluation and analysis of the page. The following describes these tools. If anyone has better tools, share them with us.
Firebug:
Firebug is the most classic development tool in Firefox. It monitors request headers and response headers to display the resource loading waterfall diagram:
Httpwatch:
Similar to firebug, httpwatch can monitor request headers and response headers to display the resource loading waterfall chart. However, httpwatch can also display gzip compression information, DNS queries, and TCP link information. individuals prefer httpwatch when monitoring HTTP requests. httpwatch includes IE and Firefox plug-ins. However, the httpwatch Professional Edition is free of charge, and the free version has some functional limitations.
Dynatrace's Ajax edition:
Dynatrace is a free tool that I often use. It not only detects resource loading waterfall graphs, but also monitors page presentation time, CPU usage, JS analysis, and execution time, CSS parsing time.
Speed tracer:
Speed trace is a plug-in of Google Chrome. The advantage of speed trace is to monitor the parsing execution time of JS, and to monitor page re-painting and backflow, this is still very strong (dynatrace can also have this function ).
Note: To install this plug-in, you need to install Google Chrome developer channel, but the link address does not seem to be available in China. If not, please download it directly at this address:

Page speed:
Page speed is a tool based on firebug. It can score pages with a total score of 100 points. It also displays suggestions for improvement. Page speed can also detect the parsing time of Js.
Yslow:
Yslow, like PGE speed, is a plug-in based on Firefox and firebug. Its functionality is similar to page speed. yslow is a Yahoo tool for rating various factors that affect website performance, I have been using it. I recommend it.
Webpagetest:
Webpagetest is a website that performs online performance testing. If you enter your url on this website, a Time Waterfall map of loading a URL is generated, showing all loaded resources (CSS, JS, image, etc.) to list the optimized list, is also a very useful tool.
