I am indeed pointing my resolv.conf to the 2 google nameservers. You're probably right about our home network. I think the router has a very low bandwidth (hardware wise), probably because it doubles up as the decoder for the TV contents being viewed on 2 to 3 different TV's in the house. TV signals come directly to the router on the coax, and then are sent back on the coax to the 3 TV sets. We're stuck with what we have.
Of course you can always use a tool such as dig to see what kind of response times you are getting.
for example....
[egreshko@meimei ~]$ dig @8.8.8.8 www.ibm.com

Shows the query took 21 milliseconds
That value is good for comparison only as it is not the real time. Take a look at this:
time dig @8.8.8.8 www.ny.com

So, the router or my super lightly loaded laptop, or the ISP, must be the cause of such delays.
