Windows desktop performance: Setting the record straight

Vista vs. XP – Windows XP is ~40% faster than Windows Vista on identical hardware(在同等硬件下XP比vista快40%). This isn’t an estimate. It’s the raw performance delta that engineers over at the exo.performance.network (www.xpnet.com) measured while testing Windows XP (SP3) vs. Windows Vista (SP1).

Now, before you blow off the numbers as being tied to Aero or indexing or some other extraneous Vista bloat factor, you need to take a look at the methodology: The lab engineers who ran the tests did everything possible to make Vista run faster. This included turning off Aero, disabling a host of background services and making Vista look and run just like XP in almost every respect. And yet, despite all of this tuning and tweaking, Vista was still roughly 40% slower than XP on the same hardware.


Bottom Line: Windows Vista is slower than Windows XP at a fundamental level – a lot slower. It’s fact. Accept it. Deal with it. Move on.

Vista vs. Server 2008 – Windows Server 2008 is up to %17 faster than Windows Vista on identical hardware(在同等硬件下2008比vista快17%）. Again, this is no estimate. And again, the test results come from the folks at www.xpnet.com.


In this case, the engineers did everything possible to slow Server 2008 down, including: Enabling Aero and the whole “Desktop Experience” feature; enabling SuperFetch, Shadow Copies and Indexing; and generally making Server 2008 look and run just like Vista. And once again, despite all the tweaking, Server 2008 came out well ahead of Vista across a variety of benchmark scenarios.


Bottom Line: Windows Vista is slower than Windows Server 2008 (a.k.a. “Workstation” 2008) at a fundamental level – quite a bit slower. And since you can easily disable/remove much of the desktop bloat from Server 2008, it’s possible to achieve even better performance using the server version of Windows as your code base.
