简单测试数据库服务器单核处理能力的程序,作者声称测试了上百个不同的U,最快的是跑在linux上的 Intel Xeon X5680 3.33GHz six-

来自Julian Dyke的测试CPU单核心性能的存储过程,能够测试CPU的单核处理能力,顺便我也测试了一把

SET SERVEROUTPUT ON

SET TIMING ON
DECLARE
  n NUMBER := 0;
BEGIN
  FOR f IN 1..10000000
  LOOP
    n := MOD (n,999999) + SQRT (f);
  END LOOP;
  DBMS_OUTPUT.PUT_LINE ('Res = '||TO_CHAR (n,'999999.99'));
END;
/

下面是一个输出结果样本:
SQL> /
Res =  873729.72
PL/SQL procedure successfully completed.

作者声称测试了上百个不同的U,最快的是跑在linux上的 Intel Xeon X5680 3.33GHz six-core , 8.92 秒。

(当然,这个脚本只是简单的测试,,并不全面。且单核的速度并不是一个CPU好坏的全部。仅供参考)

测试结果:测了几个类型的CPU,竟然是我的一台测试机(Intel Cpu)最快,秒杀HP和IBM,当然单核的处理能力仅仅是一个方面,稳定和并发才是小机的杀手锏
