In more time I used speedtest.net website. I have connection for tikona and my plan is 4mbps. I show result from this website to show me 2.5mbps. Other site tested my speed as 4mbps. But, this site always give the good result.This should be scandal for some testing takes as long as 2 minutes and still it says 2.5mbps . May be they are only testing the burst speed?. But, ISP are using it for their advantage.
Cons: -Utilizes Flash, which isn’t available in all browsers and may interfere with test results -Heavy graphics more of a nuisance than an advantage for dial-up users.
