sysbench是一款測試工具

主要包括以下幾種方式的測試：
1、cpu效能
2、磁碟io效能
3、排程程式效能
4、記憶體分配及傳輸速度
5、POSIX執行緒效能
6、資料庫效能(OLTP基準測試)現在sysbench主要支援 MySQL,pgsql,oracle 這3種資料庫

到下載安裝包.

[@more@]

我這裡只對主機做一些測試

tar zxf sysbench-0.4.8.tar.gz
cd sysbench-0.4.8
./configure –without-mysql

make

make install

比如我的 MySQL 喜歡自己安裝在 /usr/local/mysql 下，則按照以下方法編譯：

/configure --with-mysql-includes=/usr/local/mysql/include --with-mysql-libs=/usr/local/mysql/lib && make && make install當然了，用上面的引數編譯的話，就要確保您的 MySQL lib目錄下有對應的 so 文件，假如沒有，能夠自己下載 devel 或 share 包來安裝。另外，假如想要讓 sysbench 支援 pgsql/oracle 的話，就需要在編譯的時候加上引數
--with-pgsql或
--with-oracle這2個引數預設是關閉的，只有 MySQL 是預設支援的。

測試的時候注意thread數大於兩倍CPU數，測試檔案大小大於5倍記憶體大小。

拿兩臺機器，test1（8CPU，16G記憶體）和test2（3CPU，8G記憶體）來做測試

1、 cpu效能測試
sysbench --test=cpu --num-threads=32 --cpu-max-prime=90000 run
cpu測試主要是進行素數的加法運算，在上面的例子中，指定了最大的素數為 90000，

root :/root>#sysbench --test=cpu --num-threads=32 --cpu-max-prime=90000 run

sysbench v0.4.8: multi-threaded system evaluation benchmark

Running the test with following options:

Number of threads: 32

Doing CPU performance benchmark

Threads started!

Done.

Maximum prime number checked in CPU test: 90000

Test execution summary:

total time: 26.4945s

total number of events: 10000

total time taken by event execution: 837.0154

per-request statistics:

min: 0.0208s

avg: 0.0837s

max: 1.6919s

approx. 95 percentile: 0.3208s

Threads fairness:

events (avg/stddev): 312.5000/3.98

execution time (avg/stddev): 26.1567/0.25

2、執行緒測試
sysbench --test=threads --num-threads=512 --thread-yields=100 --thread-locks=2 run

thread-locks小於執行緒數除以2，lock越少，處理時間越長。

test1: sysbench --test=threads --num-threads=512 --thread-yields=100 --thread-locks=2 run

sysbench v0.4.8: multi-threaded system evaluation benchmark

Running the test with following options:

Number of threads: 512

Doing thread subsystem performance test

Thread yields per test: 100 Locks used: 2

Threads started!

Done.

Test execution summary:

total time: 2.5360s

total number of events: 10000

total time taken by event execution: 1276.9943

per-request statistics:

min: 0.0003s

avg: 0.1277s

max: 0.6007s

approx. 95 percentile: 0.3051s

Threads fairness:

events (avg/stddev): 19.5312/3.36

execution time (avg/stddev): 2.4941/0.02
3、磁碟IO效能測試
sysbench --test=fileio --num-threads=16 --file-total-size=3G --file-test-mode=rndrw prepare
sysbench --test=fileio --num-threads=16 --file-total-size=3G --file-test-mode=rndrw run
sysbench --test=fileio --num-threads=16 --file-total-size=3G --file-test-mode=rndrw cleanup上述引數指定了最大建立16個執行緒，建立的文件總大小為3G，文件讀寫模式為隨機讀。

CD到空間足夠的檔案系統，執行命令等待建立

test1:/root>#sysbench --test=fileio --num-threads=64 --file-total-size=12G --file-test-mode=rndrw prepare

sysbench v0.4.8: multi-threaded system evaluation benchmark

Threads fairness:

execution time (avg/stddev): 1.2967/0.50

我們看到兩臺機器的速度差好多，一個64M/S，一個19M/S.第二臺估計有問題，需要找找原因。測試完後記得刪除資料，否則會佔用空間。

sysbench --test=fileio --num-threads=64 --file-total-size=12G --file-test-mode=rndrw cleanup

sysbench --test=memory --memory-block-size=8192 --memory-total-size=4G run上述引數指定了本次測試整個過程是在記憶體中傳輸 4G 的資料量，每個 block 大小為 8K。

test1:/root>#sysbench --test=memory --num-threads=32 --memory-block-size=8192 --memory-total-size=512G run

5、OLTP測試

1 、準備資料
# sysbench --debug=off --test=oltp --mysql-host=10.15.2.137 --mysql-user=test --mysql-password=test --oltp-table-size=1000000 --mysql-db=test --oltp-table-name=stest --num-threads=20 --max-requests=10000 --oltp-auto-inc=off --mysql-engine-trx=yes prepare

2、測試
# sysbench --debug=off --test=oltp --mysql-host=10.15.2.137 --mysql-user=test --mysql-password=test --oltp-table-size=1000000 --mysql-db=test --oltp-table-name=stest --num-threads=20 --max-requests=10000 --oltp-auto-inc=off --mysql-engine-trx=yes run

3、刪除資料
# sysbench --debug=off --test=oltp --mysql-host=10.15.2.137 --mysql-user=test --mysql-password=test --oltp-table-size=1000000 --mysql-db=test --oltp-table-name=stest --num-threads=20 --max-requests=10000 --oltp-auto-inc=off --mysql-engine-trx=yes cleanup

指定了表最大記錄數為 1000000，其他引數就很好理解了，主要是指定登入方式。測試 OLTP 時，能夠自己先建立資料庫 sbtest，或自己用引數 --mysql-db 來指定其他資料庫。--mysql-table-engine 還能夠指定為 innodb 等 MySQL 支援的表儲存引擎型別。
