使用的tomcat版本为：apache-tomcat-7.0.53
使用测试工具Jmeter版本为：apache-jmeter-2.12
1、测试前tomat的"server.xml"配置文件（使用tomcat的默认配置，未做任何修改）
2、使用Jmeter测试工具对tomcat进行压力测试，压力参数如下：
上面我使用Jmeter工具模拟800个用户同时访问tomcat服务器，每个用户循环访问10次，共8000次请求。
3、使用Jmeter发送的数据为json字符串，POST请求写数据：
4、测试结果（聚合报告）：
我们总共发送了8000次请求，而出错率高达23.39%！就是说在8000次请求当中，有1871个请求是失败的（请求被拒绝）。因为tomcat的默认配置扛不住这么高的并发，导致tomcat的连接池处理不过来，请求直接被拒绝。
5、开始调整tomcat的配置参数，下面是调整后的server.xml配置（注意高亮部分）：
在上面的配置中，我开启了连接池 tomcatThreadPool，最大线程数 maxThreads 设置为 600，并使用 Http11NioProtocol等等。
6、使用的上面的配置，重启tomcat，使用同样的Jmeter压力参数再次进行测试，测试结果（聚合报告）如下：
把并发数从800提升到1000，再次测试：
测试结果，出错率依然为0：
7、扩展：在使用测试工具Jmeter的时候存在一个问题，就是如果使用它的GUI界面模式来测试，短时间内还凑合，时间稍微长一点，就会卡死（内存溢出）。
官方说，在实际测试的时候，千万不要使用Jmeter的GUI模式，而要使用非GUI模式，即使用命令行模式。
上面的例子都是使用的Jmeter的GUI模式进行测试的。下面是使用命令行模式来测试。下面是我们模拟的百万请求（1000个并发）测试，并发配置参数如下：
在上图中，我们模拟1000个用户并发访问，每个用户访问1000次，总共一百万次请求。
将上面的配置保存到一个命令为"friends.jmx"的文件中，然后在使用命令行模式启动它。
由于测试结果较多，不方便截图，就将命令行模式下测试过程中的输出内容复制如下：

继续，将并发数提高到3000，总共生产30万条消息（由于我的消息是通过tomcat写入到kafka的，所以使用监控工具观察到所有消息都成功被写入到kafka集群），消息全部发送成功，由于我开启了消费者，所以，所有的消息也都被成功消费：
由于我们的消息消费者是要写库的，所以，查看数据库，所有的消息都成功入库（1条消息对应数据库中的2条记录，所以30万条消息在数据库中产生60万条记录）：
观察Jmeter命令行输出：
