Hi,

I've compiled in threads to bind9.3.0 (src from isc not ports) using a dual
procssor machine (2xIntel XEON) with 5.3-STABLE and I encounter serious
performance problems (using queryperf from bind contribs):

When I compile bind without threads, the result is realistic and nearly
30x better:

Can anyone explain what's the problem here? Is this a issue of bind9 or of
freebsd? Any suggestions how I can use the two processors of my box
without running two (non multithreading) instances of bind listening on
different IPs?

Regards,

Dirk
