angela commented on OAK-8234:
-----------------------------

[~stillalex], agreed regarding no touching {{PermissionProvider}} as part of this patch. lets
track that with a separate issue... i would definitely love to leave no dead code behind.

> There was already a lot of work done here to improve efficiency of admin sessions, but
we can still do better by simply not creating many of the objects needed as parameters for
the {{CompiledPermissions}} which will be ignored anyway in the case of admin sessions.
> Ex: There are a lot of immutable trees (created via {{PermissionUtil.getReadOnlyTree(tree,
immutableRoot)}}) that are not used for the evaluation.
> Thanks to [~mreutegg] for spotting this one!
