最近用sysbench进行了较多的性能测试,也总结一下它的特点和用法和需要注意的事项。sysbench是一个多线程性能测试工具,可以进行CPU/内存/IO/数据库等性能测试。不过我绝大多数的时候都是用它来对数据库(MySQL)进行oltp测试。它能测哪些东西,怎么测让我从它的命令帮助来回答。
~/zbs$ sysbench --help
Missing required command argument.
Usage:
sysbench [general-options]... --test=
上面就大概的用法,--test=指定我们需要测什么类型,那么--test有哪几种类型呢?fileio/cpu/memory/threads/mutex,不好意思前面这几个我都没测过,我主要是用它来测数据库的性能,,但为什么没有数据库这个选项呢,这是我是用了最新的版本0.5,它与0.4的版本最大区别在于支持多表测试,执行实时打印统计信息,支持自定义lua脚本来设置测试行为。
Compiled-in tests:
fileio - File I/O test
cpu - CPU performance test
memory - Memory functions speed test
threads - Threads subsystem performance test
mutex - Mutex performance test
如果你用sysbench0.4大概会看到如下,请注意oltp这个选项就是测数据库用的。
Compiled-in tests:
fileio - File I/O test
cpu - CPU performance test
memory - Memory functions speed test
threads - Threads subsystem performance test
mutex - Mutex performance test
oltp - OLTP test
看完了测试模式之后,那么它有一些什么主要的其他控制参数呢?首先说这个每个测试模式自己特有的参数怎么擦看 sysbench --test=
