...one of the most highly
regarded and expertly designed C++ library projects in the
world.

Performance of Boost.Coroutine2 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.
