测试环境

操作系统：Rocky Linux release 9.2 (Blue Onyx)

云主机：4核8G

测试工具-sysbench

sysbench是一个基于LuaJIT的可脚本多线程基准测试工具

常用于数据库基准测试，当然也是可以用来测试主机性能。

有了这个工具，就不需要再自己写程序，就可以进行主机的基准测试。

sysbench安装

在Rockylinux上可以直接通过epel源直接安装工具。

dnf update -y epel-release
dnf install -y sysbench

CPU测试

通过sysbench cpu help可以查看对应的参数。

--cpu-max-prime=N upper limit for primes generator [10000]

默认指定素数是10000

sysbench --threads=32 --time=30 --report-interval=2 --cpu-max-prime=10000 cpu run

--threads=32：测试线程数为32

--time=30：测试时间

--report-interval=2：显示输出统计是2s

Running the test with following options:

Number of threads: 32

Report intermediate results every 2 second(s)

Initializing random number generator from current time

Prime numbers limit: 10000

Initializing worker threads...

内存测试

sysbench --threads=4 --time=30 --report-interval=1 memory --memory-block-size=8k --memory-total-size=2T --memory-access-mode=seq run

--memory-block-size=8k：指定块大小

--memory-total-size=2T：最大写入大小

--memory-access-mode=seq：seq顺序，rnd是随机

测试磁盘写入

sysbench --threads=8 --report-interval=1 fileio --file-num=200000 --file-total-size=20G --file-test-mode=seqwr prepare

生成20w个文件，总大小20G

22937600000 bytes written in 438.70 seconds (49.86 MiB/sec).

清理：

sysbench --threads=8 --report-interval=1 fileio --file-num=200000 --file-total-size=20G --file-test-mode=seqwr cleanup

总结

sysbench还有很多强大的工具，可以根据实际需要进行测试。
