I've sent PR https://github.com/keycloak/keycloak/pull/490 with first
prototype of Keycloak performance test with JMeter. For now it's using
embedded Undertow (reused KeycloakServer stuff from testsuite) also with
performance-tools, so it's easy to add new users. Most of the stuff is
configurable through System properties, which allows to easily switch
different databases and models without any needed changes in
configuration files (For example PostgreSQL, MySQL, Mongo,
enabled/disabled simple cache etc), which is also good for easy setup of
performance test in Jenkins to have it in CI. Some details in README:
testsuite/performance-web/README.md .
If you like the approach, I can continue and possibly setup CI. For now,
I've tried some testing on my laptop with 10.000 users in database and
each user having 1 realm role (available through scope to tested web
application) and 0 application roles... (I guess having configurable
number of roles, scopes per user might be useful as well and I can
possibly add it? )
Each test is using 50 clients (each client having different username, so
using users like user-0, user-1, user-49 ) and each client doing 50 test
iterations. Each iteration is doing:
- Redirect to KC login screen
- Login into KC
- Exchange code for token
- Refresh token 2 times
- Logout
Some results from test on my laptop:
