Benchmark

Date: Sat Jun 30 UTC 2018.

Machine: c5d.large on AWS.

OS: RHEL-7.5 (Red Hat Enterprise Linux 7.5).

Here is a brief summary of the benchmark part:

  • One time of the context switching between coroutines takes only about 10.29 ns (in the case of standalone stack, where x87 and mxcsr control words are shared between coroutines);
  • One time of the context switching between coroutines takes only about 10.38 ns (in the case of standalone stack, where each coroutine maintains their own x87 and mxcsr control words);
  • It is extremely memory efficient: it only costs 2.8 GB of physical memory to run 10,000,000 coroutines simultaneously (with tcmalloc, where each coroutine has a 120 bytes copy-stack size configuration).
