Dear readers,

I use

PowerDNS recursor 3.3 (C) 2001-2010 PowerDNS.COM BV (Sep 21 2010, 
18:22:46, gcc 4.4.1)

with default settings (this means I have no settings changed!) on

Ubuntu 10.04.3 LTS

The PowerDNS recursor is primary used for DNS RLBs


My main question is how I can increase the cache hit %?

pdns_recursor[17799]: stats: 317639 questions,
                               81071 cache entries,
                                8601 negative entries,
                                  8% cache hits

pdns_recursor[17799]: stats: throttle map: 2, ns speeds: 631
pdns_recursor[17799]: stats: outpacket/query ratio 96%, 0% throttled, 0 
no-delegation drops
pdns_recursor[17799]: stats: 3 outgoing tcp connections, 1 queries 
running, 5546 outgoing timeouts
pdns_recursor[17799]: stats: 57911 packet cache entries, 31% packet 
cache hits
pdns_recursor[17799]: stats: 0 qps (average over 1967 seconds)

Please can anybody point me to the right direction of link ;-O

Thanks Aleks
