Feature #10050

closed

[PATCH 0/2] reduce rb_io_t to 192 bytes (from 216) on 64-bit

Added by normalperson (Eric Wong) over 9 years ago. Updated over 9 years ago.

Status:
Closed
Target version:
[ruby-core:63781]

Description

This will allow x86-64 machines to only use 3 cache lines instead of 4
(where cache size == 64).

Hopefully there are other 64-bit architectures which benefit, too.

This is also public ABI breakage, so I hope to commit it around when a patch for
Feature #10034 (re_pattern_buffer reduction) gets committed to reduce testers'
need to rebuild C exts.
