Holy smokes! Are you saying that I can speed up compilation of D
programs by almost 3 times just by building DMD with Microsoft's C++
compiler instead of the DigitalMars one?
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.
