i use the following stanza to change the affiliation of a user to a
<iq from='admin at server.com' id=xxx' to='pubsub.server.com' type='set'
jid='user at server.com/resource'/></affiliations></pubsub></iq>
It takes about a second for ejabberd to return a result iq while all
other PubSub operations (create, subscribe, publish) are blazing fast.
This also leads to a very high system load if i run these operations in
larger batches. Is there a reason why this operation is so slow? Do you
have any hints how i could further investigate this issue? I run
ejabberd 16.06 on Ubuntu 16.04 with MySQL database (for auth and
pubsub). Thanks, Florian
