Hence doing: ```diff - auto scheduler = new FiberScheduler(); + scheduler = new FiberScheduler(); ```
Thanks for pointing it out! Looks like I was benchmarking thread instead of fiber. I just made the change you suggest but the result is very similar, that being said, using system thread or fiber does not make any obvious difference in this test case, this fact itself seems problematic, fiber should be much faster than system thread in this test case (as I have proved for many other langs with the same case, I published results [here](https://programming-language-benchmarks.vercel.app/problem/coro-prime-sieve) but note that not all of them are implemented with stackful coroutine), unless there's some defect in D's current fiber implementation.
