Recommended Web performance testing tools

WEB performance testing tools are mainly divided into three types: one is to test the page resource loading speed; the other is to test the page rendering speed and JS operation speed after the page is loaded; one is to evaluate and analyze the page in general. ~~~ If anyone has better tools, share them with us.

1. Firebug:

Firebug is the most classic development tool in firefox. It integrates HTML viewing and editing, Javascript console, and network condition monitor. It is a powerful helper for JavaScript, CSS, HTML, and Ajax development. You can monitor the request header and response header to display the resource loading waterfall diagram:

2. 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, each HTTP record can analyze its Cookies, message headers, character queries, and other information in detail. Supports HTTPS and analysis report output in XML, CSV, and other formats

3. 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.

4. 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.

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:

5. 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.

6. yslow:

Yslow, like pge speed, is a plug-in based on firefox and firebug. Similar to page speed, yslow rates various factors that affect website performance. yslow is a yahoo tool that can analyze any website, generates an overall report for each rule. If the page can be optimized, YSlow will list the specific modification suggestions. (You can analyze the website page and tell you how to optimize it based on certain rules to improve the website performance.) I have been using it for a long time. I recommend it.

7. 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.
