基准测试

编译

sysben工具地址为akopytov/sysbench)，按照官方指导编译即可。

使用

CPU测试

CPU基准测试：./sysbench cpu --cpu-max-prime=40000 run

内存测试

内存基准测试：./sysbench memory --memory-block-size=8k --memory-total-size=80G run

磁盘测试

通过创建文件随机读写方式测试磁盘性能：

./sysbench fileio --file-num=16 --file-total-size=128M --file-test-mode=rndrw prepare
./sysbench fileio --file-num=16 --file-total-size=128M --file-test-mode=rndrw run
./sysbench fileio --file-num=16 --file-total-size=128M --file-test-mode=rndrw cleanup

测试结果如下：

sysbench 1.0.20-ebf1c90 (using bundled LuaJIT 2.1.0-beta2)

Running the test with following options:
Number of threads: 1
Initializing random number generator from current time


Extra file open flags: (none)
128 files, 1MiB each
128MiB total file size
Block size 16KiB
Number of IO requests: 0
Read/Write ratio for combined random IO test: 1.50
Periodic FSYNC enabled, calling fsync() each 100 requests.
Calling fsync() at the end of test, Enabled.
Using synchronous I/O mode
Doing random r/w test
Initializing worker threads...
