From: nobu@... Date: 2018-05-05T10:13:30+00:00 Subject: [ruby-core:86896] [Ruby trunk Feature#14739] Improve fiber yield/resume performance Issue #14739 has been updated by nobu (Nobuyoshi Nakada). And seems it requires gcc (variants) and non-Windows. coro.c can't compile with Visual C nor mingw gcc. Also, `asm` needed to be replaced with `__asm__` to compile with Apple clang, and it is 3% faster. ``` $ ruby fiber_benchmark.rb 10000 1000 setup time for 10000 fibers: 0.227721 execution time for 1000 messages: 74.540142 $ ./ruby fiber_benchmark.rb 10000 1000 setup time for 10000 fibers: 0.293740 execution time for 1000 messages: 72.180107 ``` https://github.com/nobu/ruby/tree/feature/fiber-libcoro ---------------------------------------- Feature #14739: Improve fiber yield/resume performance https://bugs.ruby-lang.org/issues/14739#change-71858 * 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:
