Really helpful for rancher slowness There's been a large number of performance improvements since this issue was created. We would advise everyone to update to latest Rancher, in particular the soon to be released 2.7 Q2 version. A lot of the performance improvements UI side can be enabled via the burger menu -->

settings. In the upcoming 2.7 Q2 release there are two in particular we'd ask users to try. 1. Websocket Web Worker 2. Updates to resources pushed to the UI come WebSockets and are handled in the UI thread. Enable this option to handle cluster WebSocket updates in a Web Worker in a separate thread. This should help the responsiveness of the UI in systems where resources change often. 3. Require Namespace / Project Filtering 4. Require the user to select namespaces and/or projects when viewing cluster resources. This restricts the number of resources fetched when viewing lists and should help the responsiveness of the UI in systems with a lot of resources. We'd love to receive feedback on any of these settings, whether they assist or don't. That feedback will help us direct the next iteration of performance improvements. If these improvements don't help, we'd love to know more detail. If there is slowness where in the dashboard is worst affected? If the issue is when viewing a downtream cluster what kind of resource counts are there? Are there any failed network requested, errors in the console or message churn in the web sockets (all available via the browsers Dev Tools interface)?
