- [section:performance Performance]
- Performance of __boost_coroutine__ was measured on the platforms shown in the
- following table. Performance measurements were taken using `rdtsc` and
- `boost::chrono::high_resolution_clock`, with overhead corrections, on x86
- platforms. In each case, cache warm-up was accounted for, and the one
- running thread was pinned to a single CPU.
