I just did a very quick test using the latest DMD source:
Using the command line
-release -unittest -c
D:\DTesting\dmd.2.063\src\phobos\std\algorithm.d
DMD built with DMC takes ~49 seconds to complete, but DMD build
with VC2008 only takes ~12 seconds. (Need to get a proper VC
build done to test it properly).
Looks like the DMC build spends far more time allocating memory,
even though the peak memory usage is only slightly lower in the
VS version?
