I have an Asus rt-n16 router running the Shibby version of the Tomato firmware which includes dnsmasq version <span style="font-family:arial">2.69test3. It's in use in a building that frequently has 50+ users on a wireless network and dnsmasq has performed extremely well with very little load on the router.</span></div>
