[section:performance Performance]
|
|
|
|
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.
