Hi, I'm trying to understand the cache memory usage of unbound a bit better. I noticed that unbound-control only responds with the message and rrset cache usage so I assume these are responsible for most of the memory usage. I also notice in the tuning documentation it's recommended the rrset cache be allocated roughly twice the memory of the message cache, but on my system the message cache catches and surpasses the rrset at around 130MB using the default configuration for everything but the sizes. I really have no idea how these two caches are being used(what they contain, when they're referenced, ect.) so I'm not sure if the behavior is normal or not. I'm hoping someone can offer insight or point me towards any relevant documentation. Thanks for any input.
