whom ever it may concern
something is wrong with 7.15.1 loading kibana dashboard is extremely slow
same hardware works loading same data same dashboard in 7.12 only 14 second.
7.15.1 it takes 2 min. everything is same
I even downgraded my dev setup and put 7.12 and it works fine. just 7.15.1 had problem.
I am not going to send any data report as I don't have time nor do I have hardware to test. been fighting with this from week. finally figure this out.
Can you possibly provide the query that you are running, examples of outputs, examples of the data structure. Possibly run search profiles between the different versions, so that we can see differences?
it is just dashboard using metricbeat data and bunch of different visulization on it. nothing fency. no custom.
just finish testing on 7.14.2 and it works as it was working on 7.12.0. (both loads in about same amount of time)
7.15.1 and 7.15.0 both are extremely slow.
I understand it is vague. but it is what I am facing right now. and I have some hard target date hence no time to find out what is causing. just have to make it work. which ever version.
But using same hardware. same os. Just reinstalling ELK one by one and loading same dashboard.
I would say that something between 7.12 and 7.15 was changed and Kibana, but I did not have the time to look into all the release notes.
I had some problems with Kibana 7.15, including a discover bug, that made me postpone the upgrade until the bug is fixed, maybe there is a related issue about this slowness you are getting, have you looked into the github issues to see if it was reported?
