[ruby-core:62702] [ruby-trunk - Feature #9841] [RFC] use ihash for fstring implementation

Issue #9841 has been updated by Eric Wong. [email protected] wrote: > This results in ~100K[1] memory savings on start up (with RubyGems > loaded) with no user-visible changes. Wait, ccan htable is even cheaper in terms of memory usage. It saves ~150K at startup with fstring measured using time(1) on Debian 64-bit eglibc: http://bogomips.org/ruby.git/patch?id=bddbbfb261b59 ---------------------------------------- Feature #9841: [RFC] use ihash for fstring implementation https://bugs.ruby-lang.org/issues/9841#change-46823 * Author: Eric Wong * Status: Open * Priority: Low * Assignee: * Category: core * Target version: current: 2.2.0 ---------------------------------------- This results in ~100K[1] memory savings on start up (with RubyGems loaded) with no user-visible changes. While this is not the best example of potential ihash-related memory savings, there is zero-visible impact related to the loss of hash ordering from this change. Per-fstring entry overhead is now 24 bytes per-entry on 64-bit, half of the previous 48 bytes from st_table_entry_t. [1] as measured by the time(1) command on eglibc 2.13-38+deb7u1 (Debian 7.0 on x86-64) Related to Feature #9614 (note: I will have limited Internet access until next week, free to take your time in reviewing and responding) Also viewable via git: http://bogomips.org/ruby.git/patch?id=61c27401ed66 (1/2) http://bogomips.org/ruby.git/patch?id=67f47a356a7f (2/2) ---Files-------------------------------- ihash-fstring-only.mbox (30 Bytes) ihash-fstring-only.mbox (20.4 KB) -- https://bugs.ruby-lang.org/
