My sources at ISC tell me that thread performance with 9.3.x on all 
platforms is worse than without threads. Enabling threads by default was a 
combination of a misunderstanding on my part, and a desire to shake out some 
of the issues related to both our threads, and the BIND code. Now that we 
know (most of) the answers, with 6-release coming, and BIND 9.4 not coming 
in time, this was the right way to go.

If you were using BIND 9.2.x previously, that is to be expected. 9.3.x has 
some performance improvements over the old BIND 9 code, but as you pointed 
out the 9.4.x code base will be a substantial improvement, focused primarily 
on performance issues.

hth,

PS, thanks to Dag-Erling for the help on this one.
