DN and NDN cache are not yet being tuned as part of the auto-tuning, but
there is an open issue for me to improve this situation. [0]

As well, the NDN cache never made things "as fast" as we hoped, but I've
looked at the code and there is plenty of room to improve. I'll open an
issue about this too. [1]

Hope that helps,
