While standard nftables rules are processed by the system's CPU, kmod-nft-offload allows the kernel to "offload" established network flows directly to compatible Network Interface Cards (NICs). This means once a connection is verified and established, the hardware takes over the heavy lifting, bypassing the CPU for subsequent packets in that stream. How Flow Offloading Works

Smart Queue Management (SQM) limits bufferbloat by shaping packet queues based on configured bandwidth limits. Because flow offloading bypasses the packet processor to optimize speed, . If you prioritize low latency for gaming via SQM over raw download speeds, offloading must be turned off. 2.

: Purely code-based optimization. Works on almost any hardware but still uses some CPU cycles. Hardware Offloading

Works on almost any hardware architecture (x86, ARM, MIPS). Try again later

✅ Ideal for:

Primarily used in embedded devices, such as those running OpenWrt, to boost routing performance, particularly in scenarios where the CPU is the limiting factor. How It Works: Hardware vs. Software Offload
