Here is the test which shows coroutine arguments and `coroutine_transfer` result. https://github.com/kurocha/coroutine/blob/9bbd5e514c2e0f8f3c7c1c277aa6deb5e337a9c7/test/Coroutine/transfer.cpp#L17-L21 The reason for `COROUTINE` macro is that on win32, in order to avoid lots of stack manipulation, we need to use `__fastcall`. ---------------------------------------- Feature #14739: Improve fiber yield/resume performance https://bugs.ruby-lang.org/issues/14739#change-71988 * Author: ioquatix (Samuel Williams) * Status: Open * Priority: Normal * Assignee: * Target version: ---------------------------------------- I am interested to improve Fiber yield/resume performance. I've used this library before: http://software.schmorp.de/pkg/libcoro.html and handled millions of HTTP requests using it. I'd suggest to use that library. As this is used in many places in Ruby (e.g. enumerable) it could be a big performance win across the board. Here is a nice summary of what was done for RethinkDB: https://rethinkdb.com/blog/making-coroutines-fast/ Does Ruby currently reuse stacks? This is also a big performance win if it's not being done already. -- https://bugs.ruby-lang.org/ Unsubscribe:
