In the case that it's cached, there's a VM lock around its access that could be reduced to a lock pertaining to the class of the caller of the method. This reduces locking in multi-ractor mode and allows, for example, object allocation to happen at the same time as method calls. -- https://bugs.ruby-lang.org/ ______________________________________________ ruby-core mailing list -- ruby-core@ml.ruby-lang.org To unsubscribe send an email to ruby-core-leave@ml.ruby-lang.org ruby-core info -- https://ml.ruby-lang.org/mailman3/postorius/lists/ruby-core.ml.ruby-lang.org/
