For instances with a large number of Maven repositories/components and nested group repositories, slow performance and increased CPU usage are observed when performing UI search. This is observed particularly when performing a Maven format search (UI -> Search -> Maven) which can result in a UI timeout.
Symptom Example Thread
The main bottleneck in this case revolves around code in org.sonatype.nexus.repository.manager.internal.RepositoryManagerImpl.findContainingGroups.
