title: oidc session benchmark of Zitadel v2.70.0
sidebar_label: oidc session

import OutputSource from "./output.json";
import { BenchmarkChart } from '@/components/benchmark_chart';
The test implements [Support for (OIDC) Standard in a Custom Login UI flow](https://zitadel.com/docs/guides/integrate/login-ui/oidc-standard).
The tests showed that querying the user takes too much time because Zitadel ensures the projection is up to date. This performance bottleneck must be resolved.
