Speed up you LAN network by just over 10%.
Erratic local-networking performance. Occasionally and for no obvious reason, a Win7 LAN connection will slow to a crawl.
Just do a search on win7 slow network, and see how many hits you get for proof of this
First culprit is the Win 7's HomeGroup feature, which is enabled by default. For a description of this, there are a number of pages on MS to explain what it is. Everyone needs a network for different purposes and one network is not the same as another. It is designed to work in a wide range of circumstances, but not necessarily optimally for any of them. You also have the fact that the connection has 128 bit encryption enabled by default, something which takes time to do, and is not absolutely necessary, the old system was 56 bit encryption , which is ample.
Test done with a large fixed size file gives around 9% speed increase with HomeGroup disabled and a classic workgroup used. and a further 3% increase by changing from 128 bit encryption to 56 bit encryption.

Next, to disable HomeGroup and change encryption levels, open the Control Panel, select Network and Internet, then Network and Sharing Center. Once there, in the left-hand pane choose Change advanced sharing settings.
This will take a bit of work on your part, and you have to determine what you want, and if it is worth doing.
The easiest step is just to enable 56 bit encryption, instead of the 128 bit encryption.
