Just saw the release note of MySql 5.5. Looks exciting upgrade, but what looks most funny about the software is the fact that they claim to improve performance by 1500% on windows [some 372% on linux]. Looks great work by them. But I found this information funny, as my some Open source lover friends always claim that because of windows bad structure mysql perform bad on Windows machine as compare to linux. But now my argument to them is if it is bad structure of windows, then how they achieve 1500% improvement by improving their code and not windows ? Often people forgot when comparing software that run on multi platform that the optimization of core software can only be for either OS [if they share same code], and that cause performance issues.

But whatever it is, I am happy to see MySql perform better on windows as I am bound to use windows with kind of resources I can afford for my development and maintainability I can handle.

Good work Team !!!
