    Description

      An RW mutex was introduced to the project auth cache with https://github.com/openshift/openshift-apiserver/pull/267, taking exclusive access during cache syncs. On clusters with extremely high object counts for namespaces and RBAC, syncs appear to be extremely slow (on the order of several minutes). The project LIST handler acquires the same mutex in shared mode as part of its critical path.

          • Minor - To be worked after urgent, high, and medium priorities are resolved. This term is chosen when the severity of the issue is low, or the complexity or effort to correct it may be higher, relatively speaking. For low priority issues, known workarounds exist or are not needed due to the trivial effort needed to address the issue.
