linux benchmark 對 linux 作壓力測試的工具–unixbench

unixbench

1。測出 linux 系統整體的效能
2。結果不只取決於硬體，系統及libraries、compiler都有關系

unixbench 現在在 http://code.google.com/p/byte-unixbench/ 生活著

也已出到 5.1.3 版本了，比 4 版 多了測試顯示的功能

測試的硬體規格:

。Intel(R) Pentium(R) CPU G6950 2.80GHz
。RAM: 2G
。CentOS 5.6

我用 4.1 版及  5.1.3 版測，4 版的分數竟是 0

測試所花的時間快一個小時，真久!

5.1.3 版

不知為何有兩個分數，是因為雙核的關系嗎 !?
