RabbitMQ吞吐量测试-PerfTest上

PerfTest

RabbitMQ有一个基本的吞吐量测试工具PerfTest（文档，源代码和版本），它基于Java客户端，可以配置为模拟基本工作负载。PerfTest有额外的工具可以生成输出的HTML图形。RabbitMQ集群可能受到很多因素的限制，从基础设施级限制（如网络带宽）到RabbitMQ配置和拓扑到发布和使用的应用程序。PerfTest可以演示节点或节点集群的基准性能。

安装

PerfTest也是从Bintray和 GitHub发布的二进制版本库中分发的。如果需要将它作为库，也可以在Maven Central上使用。

Bintray:https://bintray.com/rabbitmq/java-tools/perf-test

GitHub:https://github.com/rabbitmq/rabbitmq-perf-test/releases

Maven Central:http://search.maven.org/#search|ga|1|g%3A"com.rabbitmq" AND a%3A"perf-test"

要验证PerfTest安装，请使用

使用PerfTest

运行PerfTest的最基本的方法只是指定要连接的URI，要使用的发布者（比如说1）和一些消费者（比如2）。请注意，RabbitMQ Java客户端可以实现较高的发布速率（每个连接每秒高达80至90K条消息），给予足够的带宽，并且当某些安全措施（发行商确认）被禁用时，很少需要过度配置发布者（除非这是特定的测试目标）。

bin/runjava com.rabbitmq.perf.PerfTest -x 1 -y 2 -u "throughput-test-1" -a --id "test 1"

使用2个发布者和4个消费者:

bin/runjava com.rabbitmq.perf.PerfTest -x 2 -y 4 -u "throughput-test-2" -a --id "test 2"

此修改将消费者切换到手动确认：

bin/runjava com.rabbitmq.perf.PerfTest -x 1 -y 2 -u "throughput-test-3" --id "test 3"

修改将消息大小从默认（12字节）更改为4 kB：

bin/runjava com.rabbitmq.perf.PerfTest -x 1 -y 2 -u "throughput-test-4" --id "test 4" -s 4000

使用持久队列和持久消息：

bin/runjava com.rabbitmq.perf.PerfTest -x 1 -y 2 -u "throughput-test-5" --id "test-5" -f persistent
