Taras Ledkov commented on IGNITE-7778:
--------------------------------------
The root cause of the performance drop is acquire checkpoint read lock for
in-memory cache operations.
[~vozerov], [~gvvinblade], [~agoncharuk], please review the changes of the
checkpoint read lock usage.
General purpose: don't acquire checkpoint read lock when only in-memory caches
are affected.
The patch has no performance drop for in-memory cache operations when compared
to the master branch.
> User's authentication data must be persisted on cluster with disabled
