Compared to most stock router firmware? It is fast, and more stable. May be the updated drivers or the removed junk, but WiFi, NAT and USB speeds are better on all the routers I had (my first step - install Openwrt, DD-wrt or Tomato). And no latency spikes. Lots of configuration options, extra capabilities via packages, and it can run for months without losing speed, losing the connection, becoming non-responsive or rebooting.
