I guess we speak about a bit different things. Loading time will 
increase. It can be caused by processing additional conditions and such 
stuff. But the time of each compile/link action will decrease actually 
because we will get rid of calling vcvars32.bat. That what I meant.

Some profiling will definitely help. ;-)
