This is the most common way of meassuring visitor's link speed. We've a couple of sites in Norway offering such tests for free: One is with Java and one without: http://www.dinside.no/php/art.php?id=3D94158 ('Nedlasting' is downloading, 'opplasting' is uploading) Another one: http://www.itavisen.no/services/speedometer/index.php Click on "TRYKK HER FOR =C5 STARTE TESTEN!" "Nedlastingshastighet:" shows you your download speed. The smart thing is you can include a sponsored image in your test. Those meassurements are of course innacurate but work pretty ok for most of the time. Cheers, Marcin.
