Local fix
No
Problem summary
When creating a new (e.g. ad-hoc) group, group related caches get reset and one of them gets preloaded with available groups. If the number of groups is large, a significant performance degradation can occur.
Problem conclusion
Upon group creation, no cache reset is triggered any more. Cache resets are now limited to group (property) updates. In addition, resets are limited to the concerned groups and no preload is done as consequence of a cache reset.
