Linux 性能測試工具 sysbench 的安裝與簡單使用
一 背景
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。
sysbench 支持以下幾種測試模式 ：
1、CPU運算性能
2、內存分配及傳輸速度
3、磁盤IO性能
4、POSIX線程性能
5、互斥性測試
6、數據庫性能(OLTP基准測試)。目前sysbench主要支持 MySQL,PostgreSQL 等幾種數據庫。

五 總結
5.1 對於數據庫的測試，本文未進行介紹，后續遇到該情況時會進行介紹。
5.2 由於時間倉促，文章中大部分英文本人並未進行翻譯，但是涉及到的英文都不算難。
5.3 磁盤I/O測試中，–file-extra-flags 選項比較重要，有的存儲設備是直接I/O，其他詳情還請查閱相關資料。
5.4 本文僅僅根據幫助信息整理完成，其他詳情還請參考官方手冊。

五 總結
5.1 對於數據庫的測試，本文未進行介紹，后續遇到該情況時會進行介紹。
5.2 由於時間倉促，文章中大部分英文本人並未進行翻譯，但是涉及到的英文都不算難。
5.3 磁盤I/O測試中，–file-extra-flags 選項比較重要，有的存儲設備是直接I/O，其他詳情還請查閱相關資料。
5.4 本文僅僅根據幫助信息整理完成，其他詳情還請參考官方手冊。
