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.
