Tomcat 服务器Netty+Protobuf 并发压力测试以及http测试

本文分享了一次打车软件的压力测试经验,从测试思路的确立到具体实施过程进行了详细说明,包括针对socket接口的压力测试、代码优化及问题解决等。

第一次做压力测试,真的感觉压力山大。。 但毕竟自己是部门负责人,必须要做这个事,不得不硬着头皮去面对。

首先,由于鄙人能力有限,与公司的技术总监沟通了一下,然后确定了测试的思路以及问题解决的方案。

我们公司所做的业务是打车软件。

1.理顺思路   首先,我们主要针对socket接口进行压力测试,根据业务逻辑  用户登录、订单流程等所有流程进行测试,去定位问题所在的接口,再分析代码,优化代码,如果还存在问题,也可以通过时间戳,来查看代码运行慢的部分,进而去找出问题,解决它。

2.具体测试   测试就是配置好循环让程序跑线程,基本上可以看出来一个服务器的最大负载能力,我使用过100-1000,以100递增的测试  ,服务器是Tomcat(优化过的), 当线程数达到800左右,就会开始出现崩溃的现象,Netty服务器就连不上了。 当然800左右基本还是稳定的,后来测试了1000、1500、2000 基本上每次都有崩溃的现象。不知道是不是跟服务器和Netty的优化有关。 每次跑完程序,都用jmap -heap pid命令,来查看堆信息 ,也试过jstack pid  其中有锁线程的情况,毕竟不够专业,这些东西没看太明白,下面贴出来示例

jstack 内容太多,这里就不贴了。

这是在本机的测试,还没有放到服务器真实环境里面测试。 不确定会不会性能更好一点。

目前还只测试到登陆,具体的订单业务流程还没有开始测。

第一次做测试,做得不对的,请多指教。
