Windows 7 Gigabit network tweaks, questions

[aleicgrant]

Hi there

I am running win 7 64bit ultimate going through a Linksys WRT610 v2 router. These are connected to gig capable NIC's (all computers) and cat 6 cabling.

Being a nut about getting the best speeds for file transfer etc I was hoping some LAN/network guru's can jump in and suggest settings.

I am not unhappy with my results but always look to squeeze out more.

NIC's have flow control turned off, set to full duplex 1gb and jumbo frames at 9KB

windows 7 has remote differential compression turned off.

any other tips, tweaks, suggestions

thanks to all that reply

To optimize your LAN network for faster file transfers and performance, there are several tweaks and suggestions you can try. Here are some recommendations based on the setup you described:

NIC Settings:​

• Flow Control: It's generally recommended to keep flow control enabled as it helps in managing traffic flow and reducing packet loss. You may consider enabling it and testing if it improves performance.
• Full Duplex: Setting the NICs to operate at full duplex mode is correct for a Gigabit network.
• Jumbo Frames: Jumbo frames can improve throughput in some scenarios but may not always lead to significant performance gains. You can test with different frame sizes to see if there's a noticeable difference.

Windows Settings:​

• Network Card Drivers: Ensure that you are using the latest drivers for your network adapters to take advantage of any performance improvements or bug fixes.
• TCP/IP Settings: You can optimize TCP/IP settings for better network performance. This includes tweaking parameters like TCP Receive Window size, MTU, and TCP Chimney Offload.
• File Sharing Settings: Adjusting settings related to file sharing can also make a difference. For example, enabling SMB Multichannel and opportunistic locking.
• Disable Unused Network Protocols: In the network adapter properties, you can disable protocols you are not using to streamline network traffic.

Other Tips:​

• Quality Cables: Since you are using Cat 6 cabling, ensure that the cables are of good quality and properly shielded to avoid any interference.
• Network Switch: If you have a network switch in your setup, make sure it supports Gigabit speeds and is not a bottleneck.
• Network Testing: Use tools like iperf to test network performance and identify any bottlenecks or issues.
• Network Monitoring: Consider using network monitoring tools to analyze network traffic and identify areas where improvements can be made.

By implementing these tweaks and suggestions, you can fine-tune your LAN network for optimal performance and potentially improve file transfer speeds. Remember to test each change individually to assess its impact on performance.
