Issue #14739 has been updated by ko1 (Koichi Sasada). Sorry I can't read all of your comments because it too long :p As you quoted first, > Here is a nice summary of what was done for RethinkDB: https://rethinkdb.com/blog/making-coroutines-fast/ In this article: > A lightweight swapcontext implementation It shows that `swapcontext` has extra overhead because of sigprocmask system call. > rt_sigprocmask was gone because it's not invoked by libcoro unless using swapcontext. Yes. Last year, I tried modified `swapcontext` that article introduced, and I got good performance. (I found Fiber resume/yiled ping ping and I found sigprocmask is one overhead, and google about it, and I also found same page :p) However, introduced `swapcontext` is based on glibc, so there is a license problem that we can't merge it into Ruby source code. Using libcoro (I don't see the library, but as you say) seems to use same tech, so it is one idea to employ. However, I'm not sure it is the best way. No conclusion, but it is my current comment. Thanks, Koichi ---------------------------------------- Feature #14739: Improve fiber yield/resume performance https://bugs.ruby-lang.org/issues/14739#change-71911 * 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: <mailto:[email protected]?subject=unsubscribe> <http://lists.ruby-lang.org/cgi-bin/mailman/options/ruby-core>
