angela commented on JCR-3335:
-----------------------------
while i like the general approach of separating cache reading from writing i am
not convinced that the patch would work as you replace
the 'updateCache' method with 'getEntries'.
@julian: i am not aware of such tests. i created some tests to assert that the
cache is properly cleared upon ac-modification... maybe we can
add tests for multithreaded access there?

> This is a small(ish) change that takes the 'getNodeById' cll outside of the
> synchronized block that wraps the cache access.
> I see the load call as a heavy one, and the proposed change offers better
> concurrency behavior.
> In the tests that I ran, mostly related to queries I got a 20% improvement on
> average query response time.
