Optimize Network Settings

ID/URL: optimize-network-settings

Description: Changes various Windows settings to improve network latency and speeds.

  • Applies a comprehensive set of netsh TCP/IP tweaks to disable latency-inducing features, enable fast open, offload networking tasks to hardware, fine-tune congestion control, and set optimal MTU, all to maximize speed, reduce CPU load, and improve responsiveness for gaming and high-performance internet use.
