I'd like it if you could add some instrumentation to see what accounts
for the time difference. I presume they both use the same D source code.
The code is identical, I did not change anything in the GC code. So it
uses whatever code comes with the MinGW GDC 2.058 release.
The problem with intstrumentation is, that I can not recompile druntime
for the MinGW GDC, as this is not possible with the binary release of
MinGW GDC and I did not go thorugh the effort to setup the whole build.
I'm open to suggestions though how I could profile the GC without
recompiling druntime. If someone else wants to profile this, I can also
provide precompiled versions of both versions.
I don't know what Windows has but on Mac OS X there's this application:

It lets you instrument any running application.
