The last one was when we updated from version 4.4.0 to 4.5.1 and the CPU average consumption doubled #1773 . We did some tests and and we found that the villain is the websocket.\r\n\r\n So, one of our ideas is disable the websocket losing freshness in favor of network stability #1615 (we're working on it).
