A large proportion of records are only ever used "once, or a handful of times", according to researchers: http://www.cc.gatech.edu/~ynadji3/docs/pubs/dnsnoise-dsn2014.pdf ("DNS Noise: Measuring the Pervasiveness of Disposable Domains in Modern DNS Traffic") If there were some way to only dump the most popular records from the cache (say the top 1,000 or 10,000), it would probably speed up the pre-heating process significantly and still warm the cache to an acceptable degree. Does rndc dumpdb dump the cache in DNS tree order, or could it be convinced to follow the LRU order? -- Robert Edmonds _______________________________________________ Please visit https://lists.isc.org/mailman/listinfo/bind-users to unsubscribe from this list bind-users mailing list bind-users@lists.isc.org https://lists.isc.org/mailman/listinfo/bind-users
