Since I installed Ubuntu 9.04 on my work machine (and replaced Micro$oft Outlook with Evolution), I always wondered why my download speed became surprisingly a lot faster! My surprises approached a relief today when I came across a local speed test service. I tested the speed on Windows (with no firewalls or anything coming in the middle) and Ubuntu.

The result was Ubuntu achieving DOUBLE speed than Windows! Yes you read it right, DOUBLE speed on the same machine!
I will leave you with the screenshots to witness it yourself.

Ubu download speed:

The only explanation I can tell is that the TCP/IP stack default parameters on Windows are not optimally configured, while the defaults in Linux are!
Any other suggestions?
