In our test we saw that when the dnchache was way too above the limit the system starting to swap a lot. We have quite long DNs , but I don't know the actual size.

BTW, what is the actual size that is being allocated in the memory for each entry in dncache? I know that the entries in entry cache are about twice as large as they are on disk, but I don't know about the dncache entries.
