Here is the code https://github.com/ioquatix/ruby/tree/fiber-libcoro I did some preliminary test. I don't know if there is a standard fiber benchmark/test in Ruby. I used a simple message passing ring benchmark I found. ``` ^_^ > ./build/bin/ruby ./fiber_benchmark.rb 10000 1000 setup time for 10000 fibers: 0.159232 execution time for 1000 messages: 13.581069 ^_^ > ./fiber_benchmark.rb 10000 1000 setup time for 10000 fibers: 0.153677 execution time for 1000 messages: 14.630562 ``` It was about 8% faster. I feel like this is still slow. I will need to investigate further. I didn't use stack reuse code path because I was more interested in yield/resume performance, so all fibers are allocated in the first step of the benchmark. That being said, I would like to know if this is of interest to Ruby, otherwise I won't invest more time into it. ---------------------------------------- Feature #14739: Improve fiber yield/resume performance https://bugs.ruby-lang.org/issues/14739#change-71846 * 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:
