Slow Grafana since upgrade to v7

Hello all,

I updated a few day ago to v7.1.1 from v6.x. Currently I try to migrate my stats panels.
But every time I click the “Migrate to Stat panel” button grafana slows down and is unresponsive for at least 10 seconds. If I wait and try to change anything in the settings it slows down for another 10 seconds. (Chrome or Firefox, no difference) Over and over again. With v6 there wasn’t such a problem.
My data comes from a locally installed influx database.

Any thoughts on that?


Can anybody help here?
