Boost
C++ Libraries
...one of the most highly
regarded and expertly designed C++ library projects in the
world.
— Herb Sutter and Andrei
Alexandrescu, C++
Coding Standards
This is an older version of Boost and was released in 2013. The current version is 1.91.0.
Performance of Boost.Coroutine was measured
on the platforms shown in the following table. Performance measurements were
taken using rdtsc and ::clock_gettime(), with overhead corrections, on x86 platforms.
In each case, stack protection was active, cache warm-up was accounted for,
and the one running thread was pinned to a single CPU. The code was compiled
using the build options, 'variant = release cxxflags = -DBOOST_DISABLE_ASSERTS'.
The numbers in the table are the number of cycles per iteration, based upon an average computed over 10 iterations.
