actually it depends a little in your pc performance. if you have a slow pc, the time it takes to load the page will reflect it.

i did a test, on several pc's, at work... to load vB.org. i got different values (huge ones) on winXP, win2k and win98 (P4, P2 and AMD). here there are the results:
win98(AMD) - 4.00 seconds
win2k(P2) - 2.00 seconds
winXP(P4) - 0.80 seconds
internet connection: T1 (all cases)
