...Firstly, while writing a PHP extension is obviously a lot of fun, it is unlikely to be particularly beneficial in terms of performance unless the code involves computations in tight loops. Porting “normal” components like routers to C is usually a big waste of time. You can get much better results by doing a few small improvements on the algorithmic side. For the same reason I’m not a big fan of things like Phalcon, i.e. PHP frameworks written as a C extension. You can get good performance by using an appropriate application design (that is not massively overengineered) and still retain the flexibility of keeping everything in PHP. ...

Easily turn a Ubuntu-based computer into a full linux router, complete with dhcpd, named/bind, iptables firewall, and packet inspection of the network traffic being routed. Deep packet inspection for layer 2 (mac), layer 3 (ipv4, ipv6), layer 4 (icmp, tcp, udp), and layer 7 (application-specific). Summary of network flows and all layers of inspected traffic is stored in a database at 1-second intervals. This database is then mined to drive the Apache/PHP web interface.
