Well i just taken a new internet plan - 512Kbps... Now i just knw speedtest.net... and if i run a test on it i am getting reported 10424 kb/s- Download & the upload speed is 252kb/s. So am i getting 10mb speed ??? I have ran the test over and over! Any other reputed software where i can measure the speed ??
For some reason, I also get ridiculously high results at Speedtest.net. You could try DSL Reports' speed test as it returns realistic results for me.
Here is a good one: http://www.speedtest.net/ All what you need to do is just locate your city from the map and double click then it will show you the speed of download and upload.
