You're asking specifically on Windows, and then you now want a portable 
solution. There isn't. But you could write your own compatibility layer, 
calling either Windows API functions or POSIX functions. This isn't 
rocket science. I've done that long ago and keep reusing it. There may 
of course be many third-party code/libraries doing just that if you 
don't want to do it yourself.

IME, using performance counters on Windows is the only sure way of 
getting proper resolution. Any third-party code will use them in one way 
or another. Why not do that yourself, it'll be only a few lines of code 
to write a compatibility layer.
