Granted that this could be done with a Hibernate based cache store but then again you could be wondering whether they should not just use Hibernate directly with a 2LC.

Perhaps stupid question: what does FCS stand for? :)

FileCacheStore might perform fairly well on a very good filesystem
implementation such as those available in Linux, but it can be improved
to perform even better, especially in less optimal filesystems like NTFS.

It's obviously not a high priority task, but I think we need to spend
some time on it in background for later harvest.

Cheers,
