Issue #9323 has been updated by akr (Akira Tanaka).

Status changed from Open to Feedback

Is there benchmark?

What the situation that writev is actually fast?

----------------------------------------
Feature #9323: IO#writev
https://bugs.ruby-lang.org/issues/9323#change-66887

* Author: Glass_saga (Masaki Matsushita)
* Status: Feedback
* Priority: Normal
* Assignee: 
* Target version: 2.5
----------------------------------------
I propose addition of IO#writev.
It enables gather output from multiple buffers.
If writev(2) is not available, IO#writev uses Array#join to emulate atomic write.
