After updating Graylog from version 3.0.2 to 3.2.0 I have the following problem: Web interface is very slow, I mean the time until the single-page application has been loaded into my web browser the first time(it takes ~5min).
I don’t have any issues with the network(server speed > 400mbit/s for upload/download, client speed > 50mbit/s upload/download), MongoDB(version 4.0.17) or Elasticsearch(version 5.6.0)
