Download Speed

Hello Guys see the image and see the difference but it only happen when i use rapidshare else it works good

What is the problem actually..... the pic dosen't show much but something being dloaded at 72KBPS+something else has a dload speed of 40KBPS and upload speed of 27KBPS or versa vice

the 40 KBPS is the speed shown by du meter which shows the total download speed of your DSL connection.. which in this case should be around 72... :s

Whats special in this?
