years ago, i used t use a download manager called "anti-leech" on a 128kbps connection and it used to show download speeds of more than "1mbps"... i actually thought it was true until i waited as the same 30mb file took 1 hour to download... i uninstalled the stupid program afterwards.the problem with airtel MO is that it leeches at 56kbps on a single connection... you can notice this while surfing on web pages... the page opens very slowly but a little faster than dial-up but doesn't live up to its name (edge).you notice the difference in surfing pages on 247kbps airtel MO and a normal 256kbps connection, say sify.download managers work differently because they split the downloading file in 8 different pieces (normally its 8) and simultaneously download all these 8 pieces at the same time so instead of a single 56kbps leeching connection, you get 8 times the connections and 56 times 8 is i don't know what but your hardware modem limit would be somewhere around 247kbps.rarely i get 25kbps on torrents but thats after 1am in the night.with direct downloads.. try Download Accelerator Plus... it works like a charm.
