Hi,
we are currently setting up our keycloak cluster (version 1.9.1) for the production
environment. The cluster consists of two keycloak nodes running in standalone-ha mode
whereby jgroups is configured to use tcping instead of multicast and loadbalancing is done
via modcluster. So far so good, the responses of the KC rest services are fast enough and
everthing works as expected.
The only problem what we still have is that the admin console is very slow if it is
invoked on the cluster ip. For example the request to render the realm overview page
takes more than 5 seconds
(https://${CLUSTER}/auth/admin/realms<https://$%7bCLUSTER%7d/auth/admin/realms>).
The problem is additionally increased because the GET realms request is sent up to four
times.
If we take out one keycloak node in the loadbalancer the admin console is essentially
faster. Can anyone help or does anybody have an idea what can be the misconfiguration
here? Or is this a known issue that the admin console is slow in cluster mode?
Thanks in advance!
Cheers,
sascha

Did you get anywhere with this? It's not something that we've seen or have
others report, so not sure what is going on here.
Even though the admin console is a bit heavy on the amount of requests it
performs to the server it shouldn't take 5 seconds. These are requests that
should typically be very fast.
Can you elaborate a bit on what is slow (is it all pages in the console or
just some things)? Do you have a lot of realms, users, roles or clients in
the database? Also, what does the load time of the various requests look
like, is there some that are particularly slow or are all slow?
