I just had recently a try at the new Visual Studio 2010.
I was expecting some kind of improvements over the pretty good 2008 version, whatever it could be (layout, compatibility, performance...)
In fact, quite the contrary for the last bullet point.
Binaries compiled with VS2010 are about 10% slower than VS2008. Quite a huge drop.
Anyone having noticed such an effect ? or found a solution ?
[Edit] : after a few more tests, it seems that multi-threaded programs, on the other end, benefit from VS2010. Looks like it was the emphasis of this build. But single-threaded programs seems nonetheless adversely affected.
