### [From hours to minutes: Optimizing Red Hat Developer Hub performance testing with immutable LDAP images](https://yomu.fyi/post/from-hours-to-minutes-optimizing-red-hat-developer-hub-performance-tes.md)

Red Hat Developer Hub performance testing became slow and unreliable as runtime generation of large user and group catalogs stretched environment setup and introduced synchronization failures. Previously, the framework created entries through serialized Keycloak Admin REST API operations, then waited for paginated synchronization into the Developer Hub database; concurrency could not eliminate timeouts, rate limits, or incomplete catalogs. The replacement uses immutable, pre-built LDAP container images selected by an RBAC\_POLICY-USER\_COUNTu-GROUP\_COUNTg convention, with slapadd loading seed data directly into offline LMDB files in a multi-stage build. LDAP starts with 10,000-plus indexed users, while Keycloak serves as an authentication gateway and Developer Hub waits for its initial catalog sync. Reported population time fell from 22-plus hours to 2 minutes 8 seconds for 10,000 users and 150,000 groups, while the immutable approach made tests deterministic, reduced flaky failures, stabilized baselines, and enabled larger reproducible scenarios.
