Hi Bruce,

Not sure, but could this be the kernel version of RHEL5 (which is very
old?)  Which has a 'raging herd'-bug thus only your first thread gets to
do all the work?  (I have had reports, privately, about such old kernels
showing bad behaviour).

Could it be that if you hard-line the interfaces (not 0.0.0.0 in the
unbound.conf but the exact IP value) then the OS route-selection does
not take time to determine a source interface?  (Unless you use
interface-automatic, then this does not make a difference).

You are increasing num-threads, right? (even if you compile without
pthreads, num-threads will still use multiple CPUs).

Best regards,
   Wouter
