## Performance

Performance of Boost.Coroutine2 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.

Platform | switch | construction (protected stack-allocator) | construction (standard stack-allocator)
--- | --- | --- | ---
x86_64 (Intel Core2 Q6700, Linux 64bit) | 7 ns / 20 cycles | 19 µs / cw6306445402 cycles | 10 µs / 29896 cycles
