Issue #9997 has been updated by Leonardo Bianconi. File Ruby_ppc64_benchmark.pdf added Hi Nobuyoshi, yes, my mistake. The correct results are the ones I added later. I'm attaching the results for the "Computer Language Benchmarks Game" as well. Check the time enhancement. ---------------------------------------- Feature #9997: Specifying non volatile registers for increase performence in ppc64 https://bugs.ruby-lang.org/issues/9997#change-47645 * Author: Leonardo Bianconi * Status: Open * Priority: Normal * Assignee: Leonardo Bianconi * Category: core * Target version: current: 2.2.0 ---------------------------------------- To increase performance on ppc64 machines, the registers 14 and 15 were specified for the architecture, just like for x86_64 machines. I've executed some benchmarks, see below: bm_loop_for.rb Before After real 0m2.524s real 0m2.781s user 0m2.520s user 0m2.777s sys 0m0.004s sys 0m0.004s bm_loop_whileloop.rb Before After real 0m1.142s real 0m1.267s user 0m1.138s user 0m1.263s sys 0m0.004s sys 0m0.004s bm_so_array.rb Before After real 0m1.556s real 0m1.832s user 0m1.552s user 0m1.828s sys 0m0.004s sys 0m0.004s bm_so_matrix.rb Before After real 0m1.070s real 0m1.107s user 0m1.066s user 0m1.104s sys 0m0.004s sys 0m0.004s ---Files-------------------------------- enhac_ppc64.patch (781 Bytes) Ruby_ppc64_benchmark.pdf (53.6 KB) -- https://bugs.ruby-lang.org/
