OpenWrt probably has to do everything through the CPU. Not hardware accelerated like in the stock firmware.

- wtallis 5y agoUsually a lack of hardware acceleration support is a problem on the wired side, where a lot of consumer routers rely on NAT offload in the Ethernet switch, without which a cheap MIPS core cannot offer good WAN to LAN throughput. WiFi NICs are quite self-contained these days with their own complicated firmware, to the extent that it is often hard to move enough of the processing back to the CPU even when you want to (such as to do smarter airtime scheduling than the proprietary firmware that runs on the NIC).
