Hi,
I' wondering whether there are any best practice for setting/optimizing
the values for
msg-cache-size
rrset-cache-size
key-cache-size
neg-cache-size
Is it as simple as "choose a value as big as possible" (limited only by
available resources)
or does an increased cache size also increase the time for cache
lookups? (probably not as much as having to redo the lookup via the
network?)
Is this a sensible idea:
Increase the cache sizes until the cache hit rate stops growing?
The optimize howto does not include specific information on this topic

thanks,
Christoph
