rabbitmq 和 kafka 简单的性能测试

测试环境：ubuntu 15.10 64位

cpu:inter core i7-4790 3.60GHZ * 8

内存:16GB

硬盘:ssd 120GB

软件环境：rabbmitmq 3.6.0   kafka0.8.1  (均为单机本机运行)

 PS: 测试结果均为单操作测试，即生产的时候没有消费操作

测试结果：

kafka :消费速度: 37,586 /s  生产速度: 448,753 /s

rabbitmq: 消费速度: 20,807 /s  生产速度  16.413 /s

出现问题：

rabbitmq 生产4分钟左右出现队列阻塞，无法继续添加数据，1分钟后恢复，再过大约1分钟又出现此现象并以约1分钟为间隔出现此问题。

rabbitmq 生产对象时有不小的几率(约 1/20)添加队列失败，报出的错误是“tcp链接重置”

其他并无任何问题

结论：

　　很明显的看出kafka的性能远超rabbitmq。不过这也是理所当然的，毕竟2个消息队列实现的协议是不一样的，处理消息的场景也大有不同。rabbitmq适合处理一些数据严谨的消息，比如说支付消息，社交消息等不能丢失的数据。kafka是批量操作切不报证数据是否能完整的到达消费者端，所以适合一些大量的营销消息的场景。
