Description Juan Pedro Torres univentionstaff 2025-10-07 12:40:19 CEST 
During the load test on Nubus for k8s we track some bottlenecks in UDM.

Easy improvements are to cache the call to `zoneinfo.available_timezones()` and to remove the call to `gc.collect()`. The last one was introduced in https://forge.univention.org/bugzilla/show_bug.cgi?id=28248#c3 as a precaution.
