Description Paul Weil 2020-07-13 13:01:30 UTC

In comparing the new PF4 tables to the previous version, I noticed scrolling is noticeably degraded. The PF4 table scrolling is choppy and jumpy by comparison.

See https://issues.redhat.com/browse/CONSOLE-1532 for screenshot

Comment 1 Joe Caiani 2020-07-31 20:28:59 UTC

A bug to fix the table filter has been fixed and the issue that relates to this has also been closed. adding a separate issue for table latency in the pf repo.

Comment 5 Jakub Hadvig 2020-12-23 16:10:25 UTC

We did not have time to fix this issue this sprint. Will reevaluate and try to fix in next sprint.

Comment 10 Samuel Padgett 2021-04-30 17:49:20 UTC

We are working on a new table in https://github.com/openshift/console/pull/8829#issuecomment-830248046 and might be able to look at improving scrolling performance there.

Comment 12 Samuel Padgett 2021-07-23 19:22:27 UTC

We are blocked until this is fixed in PatternFly.

Goes to pods list page with 'All Projects' selected /k8s/all-namespaces/pods, scrolling up and down, notice the performance, no big performance issue here.

Verified on 4.9.0-0.nightly-2021-08-22-070405

Let me know if there is more functions need to be checked
