Damn. I've got a little Sunfire [1] and queryperf running locally only
gets to 12k qps on a single query and 2k qps for a 1000 or so looping
around [2]. Once I hit that the udp packets drop counters start cranking
up as the bind process can't keep up.

I suspect I forgot enable the nosuck option. Can you post your config?

[1] - I don't have access to work from home so I can't post the full spec
( Quad 1.2 GHz CPUs, 16G RAM, Solaris 9, Bind 9.3.2+sec patches) or exact
config ( cache only, recursive processes, 2 views, per query logging)

[2] In other words everything is in cache.
