# Which Problems Are Solved When executing many concurrent authentication requests on a single machine user, there were performance issues. As the same aggregate is being searched and written to concurrently, we traced it down to a locking issue on the used index. We already optimized the token endpoint by creating a separate OIDC aggregate. At the time we decided to push a single event to the user aggregate, for the user audit log. See [technical advisory 10010](https://zitadel.com/docs/support/advisory/a10010) for more details. However, a recent security fix introduced an additional search query on the user aggregate, causing the locking issue we found. # How the Problems Are Solved Add a feature flag which disables pushing of the `user.token.v2.added`. The event has no importance and was only added for informational purposes on the user objects. The `oidc_session.access_token.added` is the actual payload event and is pushed on the OIDC session aggregate and can still be used for audit trail. # Additional Changes - Fix an event mapper type for `SystemOIDCSingleV1SessionTerminationEventType` # Additional Context - Reported by support request - https://github.com/zitadel/zitadel/pull/7822 changed the token aggregate - https://github.com/zitadel/zitadel/pull/8631 introduced user state check Load test trace graph with `user.token.v2.added` **enabled**. Query times are steadily increasing:  Load test trace graph with `user.token.v2.added` **disabled**. Query times constant:  --------- Co-authored-by: Livio Spring <livio.a@gmail.com>
