sysbench是一款開源的多線程性能測試工具，可以執行CPU/內存/線程/IO/數據庫等方面的性能測試。數據庫目前支持mysql/Oracle /PostgreSQL。本文只是簡單演示一下幾種測試的用法，後續準備利用sysbench來對MySQL進行一系列的測試。具體的一些參數設置，需要 根據不同的測試要求來進行調整.
編譯安裝
# wget -c http://sourceforge.net/projects/sysbench/files/sysbench/0.4.12/sysbench-0.4.12.tar.gz/download
#tar zxvf sysbench-0.4.12.tar.gz
#cd sysbench-0.4.12
#./configure && make && make install linux學習，http:// linux.it.net.cn
如果需要測試Oracle/PostgreSQL，則在configure時需要加上–with-oracle或者–with-pgsql參數
