While this post is for advanced computer users, it shows the inner workings of how an internet connection works.
Disable Remote Differential Compression (Many users state this speeds up file transfers and network transfer speeds – although many question this)
To Optimize your internet connection -
From a command prompt (administrator) type the following commands -
To return to your default settings, go to a command prompt as an administrator and type -
netsh int tcp set heuristics default
netsh int tcp set global rss=default
netsh int tcp set global chimney=default
netsh int tcp set global autotuninglevel=normal
netsh int tcp set global congestionprovider=default
netsh int tcp set global ecncapability=default
netsh int tcp set global timestamps=default
So what is heuristics? Windows Vista/7 has the ability to automatically change its own TCP Window auto-tuning behavior.
What is RSS? The receive-side scaling setting enables parallelized processing of received packets on multiple processor.
What is Chimney? TCP chimney offloading enables Microsoft Windows Vista or Windows 7 to offload all TCP processing for a connection to a network adapter.
What is autotuning? Uses a fixed value for the tcp receive window. Limits it to 64KB (limited at 65535)

If you have trouble navigating to sites and time out to Facebook or Microsoft for example, or you want to improve your download speeds -you may need to set your MTU settings -
So what do you set your MTU to? Normally your MTU is set to 1500. Every connection is different. First log into your router if you have one and set it to 1492. Retry the sites that are timing out. If this did not work, you may need to set the MTU on your network card.
Use TCPOptimizer for Windows XP -
or you can go to a command prompt (as an administrator with elevated privileges) and type -
netsh interface ipv4 show subinterface
(to see the name of your network Interface – it is important to write down the MTU settings and network interface name at this time)
To set the MTU value to 1492, type the following command at a a command prompt (Note: You MUST substitute the name of your network connection -
netsh interface ipv4 set subinterface “The Name of Your Connection” mtu=1492 store=persistent
Many users have reported an increase in download and internet speeds after adjusting their MTU to 1492. This setting may not be the optimal setting everyone.
