XP SP2 Can Slow Down Business Apps

An anonymous reader submits "Mobile PC magazine installed XP SP2 on a bunch of notebooks and benchmarked them, finding that SP2 caused a 9-percent performance reduction in business productivity apps. While a couple of notebooks performed better, the majority took a 3- to 22-percent performance hit." For now, the story is just at the top of the Mobile PC website, but they promise more details in an upcoming issue.

Not a code change.. a compiler flag change..

[bmajik]

specifically, the /GS flag to the VC++ compiler.

The compiler was modified to support automatic stack overflow checking (i.e. canaries). Server 2003 was compiled with this (and as a result, MANY things that are shared-code problems resulting in exploits on other NT based OSes are either ineffective or DoS attacks on Server 2003).

The idea is that /GS compiled binaries will cause the OS to terminate the app rather then letting code execute. The source code generally doesn't need changes.

So, its a defense in depth tactic. Ideally, there'd be no BO's in code. But there are. Terminating the program with an explanation as to why is better than letting people run code on your box. :)
