Description bpeterse 2020-01-27 20:20:44 UTC
Description of problem:

Enter a query that returns a lot of data, for example:
- https://console-openshift-console.apps.<your-cluster-id>.devcluster.openshift.com/monitoring/query-browser?query0=kube_pod_labels
- "kube_pod_labels"
- click "run queries"
- scroll down the page

At arbitrary intervals (10-20 seconds) the entire page, including sidebar menus, will flicker black for a moment.

This is a performance issue with the huge number of labels rendered to the screen by this query. (It is the table, rather than the graph that causes the issue).

I am investigating possible solutions (there are several possible approaches we can take to reduce the number of labels being rendered).

I also tried with the latest PatternFly 4.0 major release, but that doesn't help.
