sysbench 壓力測試 Linux 的 CPU、Disk、Memory

sysbench 有這些功能可以壓力測試

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

我找不到 source code (sysbench.sf.net 沒了 ?!)
不過 rpm 還有 http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm

安裝

rpm -ivh http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm

測試 CPU

sysbench --test=cpu --cpu-max-prime=2000 run

total time : 1.5542s
per-request avg : 0.16ms

sysbench 0.4.12:  multi-threaded system evaluation benchmark

Running the test with following options:
Number of threads: 1

Doing CPU performance benchmark

Threads started!
Done.

Maximum prime number checked in CPU test: 2000


Test execution summary:
    total time:                          1.5542s
    total number of events:              10000
    total time taken by event execution: 1.5530
    per-request statistics:
         min:                                  0.15ms
         avg:                                  0.16ms
         max:                                  0.34ms
         approx.  95 percentile:               0.16ms

Threads fairness:
    events (avg/stddev):           10000.0000/0.00
    execution time (avg/stddev):   1.5530/0.00

測試 IO

--num-threads 開啟線程數
--file-total-size總的文件大小
prepare，產生需要的測試文件(當下目錄)
run，開始測試
cleanup，清理測試時產生的文件

sysbench --test=fileio --num-threads=20 --file-total-size=1G --file-test-mode=rndrw prepare
sysbench --test=fileio --num-threads=20 --file-total-size=1G --file-test-mode=rndrw run
sysbench --test=fileio --num-threads=20 --file-total-size=1G --file-test-mode=rndrw cleanup

Read : 93.766Mb
Written : 62.516Mb
不過我用 hdparm -t /dev/sda 測試讀則為 226.42 MB/sec

sysbench 0.4.12:  multi-threaded system evaluation benchmark

Running the test with following options:
Number of threads: 20

Extra file open flags: 0
128 files, 8Mb each
1Gb total file size
Block size 16Kb
Number of random requests for random IO: 10000
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
Threads started!
Done.
