Thought I'd test out Microsoft Windows Live Writer which is rather slick and lightweight fat app for posting to a slew of different blogs. It has some nice functionality and will likely become my default posting app.
Anyway, I had a laptop not working right a few months back and while troubleshooting Windows XP I pulled up the network connection info box. Notice the packets sent (and compare to received). Do the math on avg packet size and divide by the 83 seconds it was up for some awesome throughput on a HP laptop!
