Yesterday i was uploading some stuff to rapidshare and i found that i was getting only 16 kbps upload speed where as i get download speed of 30 kbps. I don't know why this happened but i had to use that speed as i was upload stuff from my office which have BSNl connection. On the other hand i get 40 kbps upload and download speed from Airtel which is installed at my home.

Does anyone have any idea why there is so some speed difference between two companies.
