Debian/Ubuntu系统测试内存读写速度（非脚本机房服务器）

虽然yabs、LemonBench、融合怪等脚本都可以测试云主机的内存读写速度。但是如果在已经安装好的生产环境中，木准企服学习分享小白还是不建议使用一键脚本测试。这些脚本大部分都是安全的，但是也不排除有风险的脚本。今天教大家使用Debian源中的软件来测试云服务器内存读写速度。

需要用到的软件

sysbench

安装教程

ssh中运行：

apt-get install sysbench

使用教程

1、测试内存读取速度

sysbench --test=memory --memory-block-size=1M --memory-total-size=100G --memory-oper=read run

示例：

WARNING: the --test option is deprecated. You can pass a script name or path on the command line without any options.

sysbench 1.0.20 (using system LuaJIT 2.1.0-beta3)

Running the test with following options:

Number of threads: 1

Initializing random number generator from current time

Running memory speed test with the following options:

block size: 1024KiB

total size: 10240MiB

operation: read

scope: global

Initializing worker threads...

Threads started!

Total operations: 10240 (15526.64 per second)

10240.00 MiB transferred (15526.64 MiB/sec)

General statistics:

total time: 0.6570s

total number of events: 10240

Latency (ms):

min: 0.05

avg: 0.06

max: 1.15

95th percentile: 0.08

sum: 648.86

Threads fairness:

events (avg/stddev): 10240.0000/0.00

execution time (avg/stddev): 0.6489/0.00

2、测试内存写入速度

sysbench --test=memory --memory-block-size=1M --memory-total-size=100G run

示例：

sysbench 1.0.20 (using system LuaJIT 2.1.0-beta3)

Running the test with following options:
