How have you confirmed it?\n\nIn my opinion to solve performance issues introduced by the constant native thread proxying we need to resolve/workaround the bug that blocks greenthreads with concurrent logging.  That way we\u0027ll be able to create a single native thread at the top of the call chain instead of one per object call. \n\n[1]: https://bugs.launchpad.net/cinder/+bug/1801958","commit_id":"8aad2d54cb423c5bb4a79b258905ac7b117bb9dd"}]}
