Do you think we should start a topic on D wiki front page for 
benchmarking/performance tips to organize peoples' experience of 
what works?

I took a quick look and couldn't see anything already.  And it 
seems to be a topic that comes up quite frequently (less on forum 
than people doing their own benchmarks and it getting picked up 
on reddit etc).

I am not so experienced in this area otherwise I would write a 
first draft myself.
