现在有不少开源的跨平台软件存在,使得Linux和Windows下的软件性能有了可比性,Mohammed Saleh做了一个Ubuntu 8.04和Windows XP SP3下的软件性能对比。
测试的主要是多媒体性能和硬盘性能,前者主要是Blender、Avidemux等软件的性能测试,后者主要是采用命令行下的RAR和 ClamAV,结果显示,XP在多媒体方面大幅超越Ubuntu,而Ubuntu在IO相关程序方面更有优势——尽管测试的时候Ubuntu是ATA硬盘 而XP在SATA硬盘上。测试平台:

CPU: AMD Athlon64 X2 5600+
主板:MSI K9N Neo V3 nForce560
内存:2GB 双通道DDR2-6400 (800)
硬盘(Windows XP):WD 160GB SATA150
硬盘 (Ubuntu 8.04):Maxtor 160GB ATA133
显卡 GeForce 8600GT
两个操作系统都打上了最新的补丁.

另外他还写了一个脚本对比两者的多任务性能,结果Ubuntu大幅领先XP。
