Users of RBL's

[Chris Hammond]

Point well taken and agree 100%.  I will try different configs and see what works best.

Thanks
Chris

Fair enough, but be sure the complaints that bind is slower than product X fall
under the kind of usage you're doing.

Rbldnsd clearly blows the doors of bind or tinydns (djbdns's authoritative
server) when you're mirroring RBL zones.. rbldnsd is designed to optimize this
kind of operation. It takes a lot of short- cuts a general purpose dns server
can't. But that's OK, because rbldnsd is not a regular DNS server.

Some old comparisons (2003):
http://www.ripe- ncc.org/ripe/meetings/ripe- 44/presentations/ripe44- dns- dnscomp.pdf

Showed that tinydns was faster than bind for authoritative servers. However,
bind was clearly quite substantially faster for resolving/caching when compared
with dnscache (djbdns's resolving/caching server).

Of course, there's the old adage, there's lies, damn lies, and benchmarks. Not
to mention those benchmarks are old.

There's plenty out there with results to the contrary:

I'd run my own tests which are as close to the actual intended use as possible.
