> https://bugs.ruby-lang.org/issues/14955 One major question to ask is: does object count during application lifetime vary enough to justify freeing "struct heap_page_body"? In my experience, object count is relatively stable once an application reaches steady state, and we don't benefit from freeing heap_page_body. But then, maybe some weird applications allocate many objects at startup, and steady state object count is much smaller than startup. Anyways I made changes in mwrap 2.1.0 to hopefully answer that question by tracking heap_page_body lifetimes and deathtimes: http://blade.nagaokaut.ac.jp/cgi-bin/scat.rb/ruby/ruby-talk/439479 https://80x24.org/mwrap-public/20180811043106.GA9571@dcvr/ https://80x24.org/mwrap/Mwrap/HeapPageBody.html Unsubscribe: <mailto:ruby-core-request / ruby-lang.org?subject=unsubscribe> <http://lists.ruby-lang.org/cgi-bin/mailman/options/ruby-core>
