Performance of Boost.Context 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. The code was compiled using the build options, 'variant = release cxxflags = -DBOOST_DISABLE_ASSERTS'.
