Description dmetzger 2016-08-09 14:01:23 UTC
Description of problem:

The websocket role at present is needed to support VNC and SPICE HTML5 remote access consoles. It is enabled by default on all appliance and consumes about 150MB of memory initially (does appear grow over time when idle - possible memory leak - separate issue) and consumes CPU resources. For large installions the amount of memory consumed is non-trivial, think of sites with 100+ appliances. This memory is being consumed whether VNC and SPICE HTML5 remote access is being used with the appliance or not. The configuration screen text (and documentation) does not provide clear direction regarding when this role needs to be enabled for the end user.

It's understood that being enabled by default does simplify the POC process (if remote access consoles are being tested), however the memory & cpu usage is being carried by every appliance as a resource penalty if remote access console functionality is not required / used with the appliance. Also understood is that the effect of changing the default value within a available / supported release stream does carry the issue associated with the change in behavior.

We need to be careful here as there are plans for Async Notification / action cable to be spun off from the web socket worker.

Perhaps we can make the worker light weight. Does it need all the rails in it?

ActiveRecord is necessary.
