I don't deny in some cases BIND9 caching server may require a lot of memory and may run slowly, but if you are still using a massive number of views as you've previously reported: https://lists.isc.org/pipermail/bind-users/2008-December/074173.html the excessive number of views can be a main reason for the performance problems, in which case comparison with other implementations that don't support views doesn't make much sense. Anyway, if you want to forward incoming queries to a different server without caching the results, I believe setting max-cache-ttl (and perhaps max-ncache-ttl also) to 0 does pretty much of it. (max-cache-ttl = 0 has a bad effect, as noted in recent ARM, but if you only care about results from an external forwarder, it should be okay) --- JINMEI, Tatuya Internet Systems Consortium, Inc. _______________________________________________ bind-users mailing list [email protected] https://lists.isc.org/mailman/listinfo/bind-users
