Package: pdns-server Severity: wishlist Tags: upstream I run pdns on an apache machine, on which I also do log file analysis, which does reverse lookups. As a result, the analyser fires thousands of requests unto pdns, which seems to want to ask my pgsql backend for every single one, and only then goes out to ask the recursor to resolve the requests. This drives the system load through the roof as postgresql is answering queries it cannot answer over and over again.
Would it be possible for pdns to keep a cache list of domains it knows, so that it does not have to go and ask the backend all the time? The cache could be short-lived (10 seconds or so), even that would bring a lot of gain.
