It would be interesting to bench something extremely lightweight (like https://github.com/edubart/minicoro) against these runtimes.
By my back-of-the-napkin math, 1,000,000 coroutines would cost about 64mb + 2mb/core for stacks.. which works out to about 4x less memory than the 'winner' of this comparison, and ~30x less than go.
