We're actually currently looking at some issues around this. Please create
a JIRA and we'll make sure your case is checked as well.

Hopefully this will be solved in the upcoming 2.4 release.

> Hi,
> I'm currently using Keycloak 2.2.1 with a MySQL database. The setup I'm
> using has 2 Keycloak nodes and around 4000 client roles for one client. the
> process I go through for adding is as follows:
>    1. GET call to check whether the role already exists. (takes around
>    2000ms)
>    2. POST call to create the new client role. (takes around 10000ms)
>    3. GET call to get the newly created client role(Since the create role
>    call doesn't send the full client role in the response body). (takes
> around
>    10000ms)
> The Keycloak version I used earlier was 1.9.0 with that version this
> process worked fine with one call taking around 700ms on average.
> So as shown above this is a huge performance lag. With further
> investigation I found the following points
>    1. When using only one Keycloak node this problem doesn't appear.
>    Therefore it should be some issue with infinispan cache.
>    2. When I remove the get calls and only send the create calls then the
>    calls return in 2000ms in average.
>    3. This lag only appears when executing a get role call soon after
>    creating a client role.
> I double checked the changes for 2.3.0 [1] since there is nothing said
> about cache or related issues I raised this issue.
> Any advice or fix would be highly appreciated. Thanks in advance.
