Once an Open Access dashboard is rendered, the image is cached for 60 seconds. This means that the server does not do extra work for users viewing the same dashboard, as it just returns the cached image.
There is a new render process for each different Open Access dashboard open. So there should only be one render process if 100 users are connecting to the same Open Access dashboard.
Once a dashboard is closed and no one is viewing it, the process exits after 60 seconds of no use.
In terms of performance tweaks:
- Try to keep the dashboard scoped reasonably
- Smaller time frames for quicker query times.
- Load balance Squared Up
