Not sure what you mean by drawing a distinction between D and 
low-level languages. If you translate a piece of C code into D 
(it doesn't even require much translation since the syntax is 
similar) and compile it, you'll get the performance of C. If D 
code is slower than C, it's because you've chosen to write slower 
code for convenience/safety reasons rather than performance.
