I've found Caliper to be of good use while trying to benchmark Java code.
Thanks for the library, guys.

I'm trying to perform the same kind of benchmarking on C/C++.
The libraries available in gcc (timespec) produce a lot of noise while measuring nanoseconds elapsed.

Hadn't/Haven't you considered trying to replicate your method in trying to time C code?

If you have and didn't manage to successfully design it, may I know what roadblocks you came across?

Much of the Caliper runner is pretty Java-specific. In C/C++ you don't have to worry about JIT or GC. I'm working on a doc that explains the methodology a bit more completely, but I wouldn't expect that many of design choices for the runner would apply.

Sorry for the really unsatisfying answer.
