Issue #10081 has been updated by Nobuyoshi Nakada. PowerPC64 can unaligned access? ---------------------------------------- Feature #10081: [PATCH] Specifying MACRO for increase performence in ppc64 https://bugs.ruby-lang.org/issues/10081#change-47966 * Author: Gustavo Frederico Temple Pedrosa * Status: Open * Priority: Normal * Assignee: * Category: core * Target version: current: 2.2.0 ---------------------------------------- To increase performance on ppc64 machines, the MACRO "powerpc64" were specified for the architecture, just like for x86_64 machines. I've executed some benchmarks, see below: ~~~ Benchmark Before (milliseconds) After (milliseconds) Percentage difference bm_vm2_regexp.rb 4955 4752 -4,10% bm_so_meteor_contest.rb 6065 5817 -4,09% bm_app_pentomino.rb 35122 34886 -0,67% bm_hash_flatten.rb 3055 3011 -1,44% bm_so_sieve.rb 1227 1210 -1,39% ~~~ ---Files-------------------------------- macro_powerpc64.patch (1.16 KB) -- https://bugs.ruby-lang.org/
