Issue #18032 has been updated by mame (Yusuke Endoh). Assignee set to marcandre (Marc-Andre Lafortune) Status changed from Open to Assigned Maybe due to this change: https://bugs.ruby-lang.org/issues/15409#note-9 > reverts lazy initialization and restores overriding private methods I'm assigning this ticket to @marcandre. BTW, OpenStruct is now considered as "an antipattern", so I recommend you no longer to use OpenStruct. ---------------------------------------- Bug #18032: Openstruct is ~20..25x slower with Ruby 3.0.0 and 3.0.1 compared to earlier versions https://bugs.ruby-lang.org/issues/18032#change-92831 * Author: TiloS (Tilo S) * Status: Assigned * Priority: Normal * Assignee: marcandre (Marc-Andre Lafortune) * ruby -v: 3.0.0 * Backport: 2.6: UNKNOWN, 2.7: UNKNOWN, 3.0: UNKNOWN ---------------------------------------- Doing some timings with different Ruby versions, I noticed that when using Ruby 3.0.0 and 3.0.1 the time to create OpenStruct instances has significantly increased by 20..25x ``` 0.936016 seconds elapsed for Class.new (Ruby 2.7.2) 0.453067 seconds elapsed for Struct (Ruby 2.7.2) 1.016676 seconds elapsed for Hash (Ruby 2.7.2) 1.482318 seconds elapsed for OpenStruct (Ruby 2.7.2) 0.421272 seconds elapsed for Class.new (Ruby 3.0.0) 0.322617 seconds elapsed for Struct (Ruby 3.0.0) 0.719928 seconds elapsed for Hash (Ruby 3.0.0) 35.130777 seconds elapsed for OpenStruct (Ruby 3.0.0) (oops!) ``` see also: https://stackoverflow.com/questions/1177594/when-should-i-use-struct-vs-openstruct/5440064#5440064 Can someone please look into this? ---Files-------------------------------- OpenStruct_timing.rb (1.04 KB) -- https://bugs.ruby-lang.org/ Unsubscribe: <mailto:ruby-core-request@ruby-lang.org?subject=unsubscribe> <http://lists.ruby-lang.org/cgi-bin/mailman/options/ruby-core>
