Working on a C++ app that I also use regularly, I've noticed that my debug builds seem to run really quickly now that I'm running x64 versions. i.e. There's much less slowdown with debug vs release than there was on x86.
I wonder if that's a real effect of x64 itself -- e.g. due to x64 compiler/asm differences -- or just something I'm imagining or the side-effect of my system having more available RAM or something?
I used to hate using a debug build but now I'm happy to use it all the time.
Whatever's behind it, I like it!
