There is more windows 7 tuning possible.. Here are some extra things to test.
read this site before changing anything run : netsh int tcp show global and write down your defaults. http://betanews.com/2011/01/20/use-hidden-windows-tweaks-to-speed-up-your-internet-and-network-connections/ and extra Disable Windows Scaling heuristics also for some quick service tuning. look here. http://www.blackviper.com/service-configurations/black-vipers-windows-7-service-pack-1-service-configurations/ I've disabled ** Windows Media Player Network Sharing Service With large music collections, this eats your cpu. and it corrupts your media player database. ** Windows Search i dont use windows search... and there is one at software / windows components. Remote Differential Compression, remove the V. and reboot. This are the things i did for tuning my win7. My server is a E350 running at 0.8-1.6Ghz, 2 x 3TB Software Raid 1. (mdraid) ( 5400 rpm ) and i do the max ( 125Mb/s) when i copy large files. ( ubuntu 12.04.2 LTS 64Bit ) the 3 TB are 3 partions, the movie partition had 4mb blocksite. ( optimized for large files ) and this is done while running xmbc, downloading and playing movies. The first things i would try are. - disable Remote Differential Compression ( remove ) - disable Windows Search - disable Windows Media Player Network Sharing Service try these before changing anything from above sites. this one is the most noticable : netsh interface tcp set global autotuning=disabled and you did that one already.
