<h3><a name="PerformanceTestReport-zh-%E6%B5%8B%E8%AF%95%E8%AF%B4%E6%98%8E"></a>测试说明</h3>
<p>a、本次性能测试，测试了dubbo2.0所有支持的协议在不同大小和数据类型下的表现，并与dubbo1.0进行了对比。</p>
<p>b、整体性能相比1.0有了提升，平均提升10%，使用dubbo2.0新增的dubbo序列化还能获得10%~50%的性能提升，详见下面的性能数据。</p>
<p>c、稳定性测试中由于将底层通信框架从mina换成netty，old区对象的增长大大减少，50小时运行，增长不到200m，无fullgc。（可以确认为mina在高并发下的设计缺陷）</p>
<p>d、存在的问题：在50k数据的时候2.0性能不如1.0，怀疑可能是缓冲区设置的问题，下版本会进一步确认。

<h3><a name="PerformanceTestReport-zh-%E6%B5%8B%E8%AF%95%E8%84%9A%E6%9C%AC"></a>测试脚本</h3>
<p>1、性能测试场景（10并发）</p>
<p>a、传入1kString，不做任何处理，原样返回</p>
<p>b、传入50kString，不做任何处理，原样返回</p>
<p>c、传入200kString，不做任何处理，原样返回</p>
<p>d、传入1k pojo（嵌套的复杂person对象），不做任何处理，原样返回</p>
<p>上述场景在dubbo1.0\dubbo2.0(hessian2序列化)\dubbo2.0(dubbo序列化)\rmi\hessian3.2.0\http(json序列化)进行10分钟的性能测试。 主要考察序列化和网络IO的性能，因此服务端无任何业务逻辑。取10并发是考虑到http协议在高并发下对CPU的使用率较高可能会先打到瓶颈。
<br class="atl-forced-newline" /></p>
<p>2、并发场景（20并发）</p>
<p>传入1kString，在服务器段循环1w次，每次重新生成一个随机数然后进行拼装。</p>
<p>考察业务线程是否能够分配到每个CPU上。
<br class="atl-forced-newline" /></p>
<p>3、稳定性场景（20并发）</p>
<p>同时调用1个参数为String（5k）方法，1个参数为person对象的方法，1个参数为map（值为3个person）的方法，持续运行50小时。
<br class="atl-forced-newline" /></p>
<p>4、高压力场景（20并发）</p>
<p>在稳定性场景的基础上，将提供者和消费者布置成均为2台（一台机器2个实例），且String的参数从20byte到200k，每隔10分钟随机变换。

<h4><a name="PerformanceTestReport-zh-"></a><font color="#000000">6.1</font> <font color="#000000">性能分析评估</font></h4>
<p>&nbsp; Dubbo2.0的性能测试结论为通过，从性能、内存占用和稳定性上都有了提高和改进。由其是内存管理由于将mina换成netty，大大减少了1.0版本在高并发大数据下的内存大锯齿。如下图：</p>
<h4><a name="PerformanceTestReport-zh-"></a><font color="#000000">6.2</font> <font color="#000000">性能对比分析</font><font color="#000000">(</font><font color="#000000">新旧环境、不同数据量级等</font><font color="#000000">)</font></h4>
<p>Dubbo2.0相比较Dubbo1.0（默认使用的都是hessian2序列化）性能均有提升（除了50k String），详见第五章的性能数据。</p>
<p>出于兼容性考虑默认的序列化方式和1.0保持一致使用hessian2，如对性能有更高要求可以使用dubbo序列化，由其是在处理复杂对象时，在大数据量下能获得50%的提升（但此时已不建议使用Dubbo协议）。</p>
<p>Dubbo的设计目的是为了满足高并发小数据量的rpc调用，在大数据量下的性能表现并不好，建议使用rmi或http协议。</p>

<p><font color="#000000">由于</font><font color="#000000">dubbo</font><font color="#000000">本身的性能占用都在毫秒级，占的基数很小，</font>性能提升可能对应用整体的性能变化不大<font color="#000000">。</font></p>
