djbdns 1.05 queries to roots

  While 1MB is the default cache size for djbdns, compared to a 100MB cache, 
  the 1MB cache increases the load on the TLD and SLD nameservers 
  by a factor of 4, and increases root server load by a factor of 10.   
  To avoid this, we simulated with only the 100MB cache.

  djbdns 1.05 (100M cache) uniformly distributes its queries to roots and .com TLDs in all 
  three experiments.  Increased query load in the linear delay experiment (blue) is an 
  artifact of our simulation because the caching name server repeats queries before 
  a response is cached.  (Note that this effect does not occur in BIND9.)
