View Full Version : [ubuntu] TCP/IP question

January 22nd, 2011, 01:14 AM
I want to ask the community if Ubuntu's implementation of the TCP/IP stack is more, or less, efficient when compared to Microsoft's implementation? I have found when working with XP, Vista, and to a lesser degree, 7, that the stack requires an enormous amount of tweaking to get decent throughput with an acceptable amount of packet loss. I have never been able to figure out if this has been poor engineering on Microsoft's part, or just conservatism to the point of ineptitude. I have searched through the forums for a guide that would assist me in tuning Ubuntu but haven't found anything. If someone could point me in the right direction with this it would be greatly appreciated.

I haven't noticed any difference between Windows and Linux in that regard.

The stack in recent Windows implementations has some built-in limits on the number of multiple connections (http://serverfault.com/questions/51597/how-to-fix-tcp-ip-has-reached-the-security-limit-event-message) that can exist at one time. These were supposedly added to protect against problems from malware. They also pose a problem for BitTorrent users since BT routinely sets up dozens of connections to peers.

There's nothing like this in the Linux networking stack that I know of.

Thank you for your replies. I thought that might be the case considering the nature of Linux and the Linux community. It is always such a nightmare when dealing with Windows.
