Hey,
I've just installed a Soekris 6501 at a school with 80 students and 50 Mbit, but I am surprised over the high CPU-usage (See image). The router runs Captive Portal and a few firewall rules and Squid Guard for blocking Facebook.
The plan was also to install Snort for detection of P2P, but it seems that there is no more CPU power left to handle that?
