I don't care about benchmarking, I care about writing large, fast 
systems. Small toy programs are irrelevant because they are not 
representative of real programs. Real programs are large (many 
thousands or millions of lines of code) and you don't have the 
luxury of being able to hand optimize every line of code.

Commercial market for what? For high performance applications C++ 
is still champion.

D is getting there. Remedy Games are sponsoring DConf, and I 
predict we'll start to see some high quality indie games over the 
next few years written in D. Up till now, I imagine language 
stability has been the main thing holding back D. Tomasz was 
working on a high quality renderer before he got fed up with D's 
instability (http://h3.gd/code/nucleus/).
