I've just read the article over at Dr Dobbs by Walter
http://www.drdobbs.com/cpp/increasing-compiler-speed-by-over-75/240158941
and this line caught my eye:
Even if you know your code well, you're likely wrong about where
the performance bottlenecks are. Use a profiler. If you haven't
used one on your codebase in a while, it's highly likely there's
a bottleneck in there that's fixable with just a few lines of
code.
What profilers do you use with D especially for Linux and Mac?
I've been compiling with -profile and trying to grok the output.
