After roughly 2 years( http://www.digitalmars.com/pnews/read.php?server=news.digitalmars.com&group=digitalmars.D&artnum=12277 )
I've generated new test results for OOPack:

While the gaps between GCC, GDC and DMD have narrowed, "Complex" still
poses a serious problem for GDC and DMD.

The C version of "Iterator" seems to be surprisingly hard for DMD:
DMD / GDC / GCC = 243.902 / 733.945 / 733.9 Mflops

It would be interesting to see how DM, DMD and GDC compete on a
MSWindows system.
