If your like most home/office network tweakers looking for every bit of performance you can squeeze out of your home network. For $49 the small, yet powerful Ubiquiti ER-X is a great value offering gigabit ports, PoE, small form factor and VPN functionality.
As with any router the manufacturers release software updates periodically that offer fixes, security patches and added features. In once example, enabling hardware offloading on the Ubiquiti ER-X models.
Offloading is used to execute functions of the router using the hardware directly, rather than a process of software functions to greatly increase performance. The benefit of enabling offload in EdgeOS is increased performance and throughput by not limiting the performance to the CPU.
