We have a Jira environment for 2000 users on Jira server v8.9.1 testing Advanced Roadmaps. We have a test environment with just a few projects and almost none issues. When we set-up a plan that consists of 2 other plans in total about 12 teams.
If we are using the new improved interface the response time of the system is between 45 seconds and 1 minute to just load the plan overview. Selecting filters will also take another 45 seconds or more and any selection box will take another 30 to 45 seconds.
However, the moment we switch off the improved interface we have excellent response times with the same actions.
Can we control this in any way?
