Steps to reproduce

Client used https://github.com/jjqoie/nctalkclient Same user makes more than one poll/wait API request in parallel to different chatrooms(tokens) /ocs/v2.php/apps/spreed/api/v1/chat/${this.roominfo.token}?lookIntoFuture=1&setReadMarker=1&format=json&lastKnownMessageId=${this.lastmsgid}

Expected behaviour

Should work with out slowing down nextcloud and making it less responsive.

Actual behaviour

With one request to one chatroom everything is fine. 2 or more parallel requests of the same user to differnt chatrooms(tokens) makes the nextcloud instance slow and less responsive. Slow means that for example when a new talk message is entered it takes sometimes up to 30 seconds until it was sent, but also switching between the other nextcloud tabs is less responsive… It looks like the delay is releated to the timeout parameter send with these requests. I have tested this also on a new nextcloud instance running in a VM, same behaviour.
