My usual estimate is about twice as fast, but it depends on what you 
compile. It doesn't have a huge effect on running the test suite, my 
guess is that the runtime initialization for the MS build is slightly 
slower than for the dmc build, and there are a large number of small 
files to compile there.
Also, it's quite difficult to get accurate and reproducable benchmarking 
numbers these days, with the (mobile) processors continuously changing 
their performance.
