However, I never see single digit delays!

'dig google.com' just out of curiosity.  The first response took 66

My machine is nothing special (Athlon 1<>2 GHz). *
**Yes, I considered that it might be this ancient box, but it can ping
itself in less than 100µs!

I intend to try it on one of the faster computers I have but this is
my primary box.  An old Pentium III 450 mHz w/~400 megs of RAM.  And
this is the one I am most interested in, everything I do seems to be
done here.  So maybe single digit times are out of the question?

I get 3 msec on a dual PII 450 on the 2nd query for
www.google.com:

*I wonder if my system may be introducing unanticipated [by me] delays? I am assuming that the DNS process is internal to my computer once an
address has been cached however I have an ethernet switch, a wireless
bridge, and a wireless router that may be sneaking into the picture by
some means not obvious to me?

I have a system diagram at http://users.wildblue.net/bobgoodwin/system.png. The computer I am using is labeled box1.
