<p class="MsoNormal">Folks,<o:p></o:p></p>
<p class="MsoNormal"> Recently been looking at servers that host almost 200K ARPA zones and load about 80 million resource records. They run on good hardware and take only a few minutes to load the zones on a clean start. The issue is memory
utilization of about 23 Gig in RAM.<o:p></o:p></p>
<p class="MsoNormal"> It seems a terrible waste of memory and a good portion of those zones probably rarely see queries.<o:p></o:p></p>
<p class="MsoNormal"> <o:p></o:p></p>
<p class="MsoNormal"> I’ve got extensive experience with mySQL and postgres, but always assumed you’d really take a latency hit. Plus, we’d be adding more complexity by running a DB server. The current DNS servers are located in separate data
centers – it seems we’d have to also run a master/slave DB setup, with a slave DB server at each site to avoid network overhead. This all sounds very slow and more complicated.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"> Anyone with experience solving this type of issue?<o:p></o:p></p>
<p class="MsoNormal"> Many thanks!<o:p></o:p></p>
