 I didn't have a chance to look into this much, but opening ticket so it is
 not forgot.

 With a server with 100,000 zones of 15 records each loaded into sqlite3
 database, queries that result in nxdomain had a qps regression.

 This is from 1.1.0 to 1.2.0beta1

 largehost-sqlite3-cpus4.nxdomain 12448.86 - 3956.23 qps 68% regression

 largehost-sqlite3-.nxdomain 3199.41 - 1023.14 qps 68% regression
