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