Why the whole recursive server, with all the heavy chasing, server selection,
checking of DNSSEC signatures, ACLs, …?

Why not just the cache from the recursive server? If we make the effort and make
that one fast, we could replace the (possibly unoptimized) hot-spot cache.

It may be also possible the slowdown is somewhere in the processing, not in the
cache itself. Then I don't see how anything from the recursive server could help
us.

Have a nice day
