Jukka Zitting commented on JCR-2770:
------------------------------------
+1 Alternatively we could just set the initial size to the default 16 as the
resize logic shouldn't really affect performance to any notable degree.
> Initial size of ConcurrentCache depends on number of segments (available
> processors)

> This causes a build failure on my machine. Tests run into an OOME because the
> initial memory footprint of a ConcurrentCache on my machine is 8k. Many of
> the tests keep references to some kind of repository objects (node, session,
> x-manager), which means ConcurrentCache instances cannot be garbage
> collected immediately after a test run.
> I think the overall initial size of the cache should be independent of the
> number of segments. See proposed patch.
