 I tried to load a large zone (over 3M records) by b10-loadzone. It took
 over 5
 minutes, taking 100% CPU. Large part of the time is probably datasource
 handling (in this case the sqlite3 library). It may be worth trying to do
 the
 parsing in one thread and pass batches of RRs to a second thread that'd do
 the
 writes.
