Zitat von Steve Snyder <[email protected]>:
Hello.
I am very new to unbound. I've used BIND for years, though, so I
understand the DNS concepts. Mind if I ask a few questions?
Below is my unbound configuration and farther below are the stats
from an 18-hour run of unbound. I am running RHEL 5.7 on a
dual-core CPU with SMT enabled (i.e. the OS sees 4 processors) with
plenty of RAM. Unbound was built against the current versions of
it's dependencies, except for version 2.5 of GLibC.
1. I built unbound with the libevent library because I read that it
improved scalability, which seemed reasonable given that I can run 4
threads simultaneously. After 18 hours with what I think is a
representative load I get this:
info: server stats for thread 0: 622 queries, 98 answers from
cache, 524 recursions, 10 prefetch
info: server stats for thread 1: 18161 queries, 3186 answers from
cache, 14975 recursions, 265 prefetch
info: server stats for thread 2: 15963 queries, 2746 answers from
cache, 13217 recursions, 248 prefetch
info: server stats for thread 3: 1064 queries, 179 answers from
cache, 885 recursions, 20 prefetch
Hm, with this kind of traffic you are well served with the stock
defaults. You can start worry about Unbound tuning if your
queries-per-second reaches at least some hundreds.
Regards
Andreas
