## Performance

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'.

Table 1.1. Performance of context switch

Platform | ucontext_t | execution_context (v1) | execution_context (v2)
--- | --- | --- | ---
x86_64 [a] | 547 ns / 1433 cycles | 51 ns / 141 cycles | 7 ns / 18 cycles
