Ubuntu 8.04与XP SP3性能大比拼
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。

Misc:
Tests were run on fresh installs of Ubuntu 8.04 and Windows XP SP2 with SP3 on top with only latest updates, media codecs, hardware drivers and test programs installed.
Desktop effects on both Windows XP and Ubuntu were ON.
nVIDIA-supplied VGA drivers on both (v175.16 for Windows XP and v169.12 on Ubuntu)
Disabled Paging/Swapping on both Windows and Linux to limit disk IO effect on CPU/RAM tests (RAR compression, GIMP, Blender, MP3 Encoding)
Data=Writeback Journaling on the EXT3 hard drive.
Disabled NTFS last-access time stamp on the NTFS hard drive.
All test read/wrote from/to the same hard disk partition: EXT3 for Linux and NTFS for Windows
