性能/压力测试工具 JMeter 2.5 发布

     <a href="http://www.open-open.com/open21026.htm" target="_blank">Apache JMeter </a>是100％的Java    <span class="innerlink">桌面</span>应用    <span class="innerlink">程序</span>。用于对    <span class="innerlink">软件</span>做压力    <span class="innerlink">测试</span>（例如Web应用）。JMeter可以用于测试静态或者动态资源的性能（文件、Servlets、Perl脚本、java对象、数据库和查询、ftp服务器或者其他的资源）。 JMeter用于模拟在服务器、网络或者其他对象上附加高负载以测试他们提供服务的受压能力，或者分析他们提供的服务在不同负载条件下的总性能情况。你可以用JMeter提供的图形化界面分析性能指标或者在高负载情况下测试服务器/脚本/对象的行为。    <br />    <br /> 另外，JMeter能够对应用程序做衰退测试，通过创建带有断言的脚本来验证你的程序返回了你期望的结果。为了最大限度的灵活性，JMeter允许使用正则表达式创建断言。    <br />    <br /> 项目地址：    <a href="/misc/goto?guid=4958185195964114592" target="_blank">http://jakarta.apache.org/jmeter/</a>    <br /> 相关文档：    <a href="http://www.open-open.com/doc/search?q=jmeter&ft=all&od=0" target="_blank">http://www.open-open.com/doc/search?q=jmeter&ft=all&od=0</a>    <br />    <br />    <p>JMeter 2.5 发布了，该版本包含很多新特性和大量的bug修复，另外该版本要求 Java 1.5 或者更新版本。</p>    <p>主要改进内容：</p>    <ul>     <li>The HTTP implementation can now be selected at run-time, and JMeter now also supports Apache HttpComponents HttpClient 4.x.
