Hi I tested against www.google.com and I dont see a zero latency. did you verify with View Results Tree that you are indeed getting Google's home page (no redirects/errors or anything)? are you seeing this behavior for all external sites?
The elapsed time = latency +( time from 1st byte to last byte received). Any combination of value is possible , with elapsed time always greater than latency. regards deepak On Sat, Jan 9, 2010 at 10:11 PM, Jatin <[email protected]> wrote: > I was testing from my home laptop.
