How to increase uploading and downloading speed?

[poor]

Thanks now it cleared my doubt, but I think some other sites like mediafile, hotfile are offering more than rapidshare, so I wonder why some people are still sticking to rapidshare. Maybe they are very old if I'm not wrong.

yeah rapidshare is more famous than all other file hosting sites , mostly i see people uploading files to rapidshare , so people prefer to buy premier account there , other sites are not really used as much as them.
