Visual C++ 2005 Express Issue

I am mostly into scripting and my C++ is not what it should be. I wanted to do a fresh recompile from source, I am using 1.4 not head, all workied well thanks to the online folk, but my game seemed slow. When I checked the file size to the original I found the original compile ,from GG, was 1.07 M my compile, no change to code was 7.10 M, Like I said it works but it has slowed my game down a lot. Any Ideas
