Just set the run_bind9_faster parameter to 1.
Seriously, Linux kernel tuning is a complex subject, about which many
papers have been written and possibly even Ph.D.'s wrought. Not to
mention, different traffic profiles and/or query mixes might require
tuning of different kernel variables.
Speaking in incredibly broad terms, named as a caching/recursive
resolver is going to beat up your memory subsystem far more than your
CPU number-crunching capacity or I/O. So the first place to look would
be your paging and swapping metrics and/or parameters.
Or, just throw more memory at it. named finds that very tasty.
