Jmeter官网：http://jmeter.apache.org/
官网上信息和资料还是很全的，英语好的同学完全可以跟着官网来学习。
基本介绍：
Apache Jmeter is a 100% pure Java application designed to load test client/server software ( such as a web application). It may be sued to test performance both on static and dynamic resources such as static files, Java Servlets, ASP.NET, PHP, CGI scripts, Java objects, databases, FTP servers, and more. Jmeter can be used to simulate a heavy load on a server, network or objected to test its strength or to analyze overall performance under different load types.
Additioanly, Jmeter can help you regression test your application by letting you create scripts with assertions to validate that you application is returning the results you expected. For maximum flexibility, Jmeter lets you create these asserations using regula experssions.
But pls. note that Jmeter is not a browser, it works at protocal level.
