LAN Bandwith and File Transfers

try updating the drivers of your mobo or setting your nic card to 1000 instead of auto

I tried turning to 1000 full on both machines, but still have the same issue. I also turn off all energy efficient settings and green settings. The newest drivers were installed from the web during my initial configuration less than a month ago. I will reinvestigate the drivers though.

thinking maybe your PC cant handle that high of mtu level... but you said you tried it normal at 1500 correct

also do yo gave fiber connecting to your switches?

When I changed the MTU it was originally set at 1300 on both machines. I had never previously changed this so I'm not sure why its not at 1500. At either 1300 or 9000 the performance is the same. I try 1500 too just to say I did.

when you say it was at 1300 on both machines do you mean the router was config to 1300 because or did you do a regedit on your win7 machines?

Here is what is was set to:

C:\Users\sgaron>netsh interface ipv4 show subinterfaces

MTU MediaSenseState Bytes In Bytes Out Interface
------ --------------- --------- --------- -------------
4294967295 1 0 1046 Loopback Pseudo-Interface 1
1300 1 12591931404 271635974 Local Area Connection


I used this command to change the MTU:
netsh interface ipv4 set subinterface "Local Area Connection" mtu=9000 store=persistent

and for the router whats the mtu on that?

Where did you disable QOS? on the router or in both PC's? You will also have to disable QOS on both machines, here is one way http://pcsplace.com/tips-n-tricks/best-way-to-increase-...). But that only accounts for 20%...

You could turn off DHCP services, and set both PC's to static. This should eliminate some network chatter.

You could also try disabling "Nagle’s algorithm"/ TCP no delay  http://lifeandcode.net/2009/05/reduce-game-network-late...). This basically says, do not wait for a packet to reach a certain size, send NOW what you have.

Also you might find this Link helpful http://forums.malwarebytes.org/index.php?showtopic=2662... . There are a few things there I just found out and thought they were interesting.

In PC's (home/business's) I have never seen a PC transfers above 50%, servers are different... And to increase your speeds, you are going to have to dig deep into the TCP/IP stack, and get rid of any kind of excess fat...

Most of the links are for "gaming", but they should help with file transfers as well... Just some thoughts, it might help.
