Bryce Lelbach told me they didn't move to Boost.Context because it was slow and had significant scalability problems. I had asked him to give his experience during the Boost.Context review, but it seems he never did.
I did a performance test (included in my lib -> directory performance) which measures the costs of a context jump. the result of Giovannis Boost.Context and my implementation (whic hyou told is slow and significant scalability problems): CPU cycles per jump with enabled BOOST_ASSERT (1000 iterations, average of 10 executions): - Giovannis implementation : 561 cycles - my implementation: 371 cycles CPU cycles per jump with disabled BOOST_ASSERT (1000 iterations, average of 10 executions): - Giovannis implementation : 556 cycles - my implementation: 337 cycles
