	Correct.  Ancient Pentium-133 laptops with 48MB of RAM and 
originally shipped with a 1GB hard drive (state-of-the-art about ten 
years ago), running BIND-9 on reasonably recent versions of FreeBSD 
can easily sustain query rates much higher than this.  More modern 
machines should be able to easily sustain query rates into the 
thousands of queries per second.
