openfire 4.0.1 slow performance

[hugokoopmans]

Hi,

I have used this docker succesfully to initialize a working openfire 4.0.1 container.
Works great but ...

I have really bad performance.

I have opened a threat on the openfire forum here but maybe someone here can also point me in the right direction to tune the docker container.

The JVM uses 120MB of the claimed 880 MB which according to the openfire docs would be sufficient for well over 500 concurrent users.

If I look at docker stats

I can see the openfire container (first line) actually uses 367 MB so no swapping or anything wierd afaik.

The tail of the log tries to close sessions which are no lionger used not sure how to get ride of these.

Tail log:

2016.06.08 10:03:30 org.jivesoftware.openfire.http.HttpSessionManager - Closing idle session: hugo@sccss-test.sensingclues.com/7ljbb8wp6a

Performance is 30 seconds + up to minutes...

Any clue or direction how to tackle this?
