who made mili and micro so darn alike?

IIRC you can use C's stuff.

Might I suggest std.perf?

I found it here some years ago:
http://www.digitalmars.com/techtips/timing_code.html

It even seems to have survived the transition from D1 to D2.

Oddly enough, this rather useful module never seems to never be included
in the web documentation.  :(

Just read the comments in the source file that comes with your compiler.
{dmd-path}/src/phobos/std/perf.d

I've always used PerformanceCounter with good results.

I also use it.  Why does it not get inserted on D1 and D2?

thanks,

std.perf was added *years* ago, in D's infancy. It wasn't even written
by Walter, so the docs never made it into the DM pages. The
documentation embedded in it isn't even DDoc, it's Doxygen. It's
always been sort of a misfit.

That hasn't been true for over a year.  I cleaned it up a while back
and made sure it worked with D2 [1].  The doc comments are all DDoc
now.  See for yourself [2].   Just hasn't been added to the index for
some reason.
