Windows 7: Speed problem

Hey there
I'm subscribed to 8mb/s connection. There's no connectivity issue, no disconnects but the porblem is speed. My few YouTube videos buffer, downloading speed normally from sites is 200-300 kb/s. Only few sites like Ubuntu, Microsoft sometimes gives me full speed. Is there any problem with my network connection or the sites can't provide me full download speed?

There are no problems with your connection. You are getting your normal speed.
For example in first download from Ubuntu (Saudi Arabia server) you got around 850 kb/s which is normal for your 8 mb/s bandwidth.
On second download you tried from Great Britain server and you got lower speed because server is far away from you, so you will get speed reduction. Same goes to Youtube, original server far away form you...

yeah your internet seems perfectly fine, you had a MS ping of 16. Not too bad.

so if you have any grips or complaints about the speed, you need to take it up with your Internet Service Provider becuase your computer is working perfectly fine.

hmm my server provider says the same, server too far from you. Thanks for replies.
