Description

When 700+ Captive Portal users are in use, CPU interrupts will cause high load averages to occur. This can lead to connectivity problems, such as packet loss on WAN uplinks, webConfigurator responsiveness issues, etc.

Tested with a customer who had load averages of 14-16 with Captive Portal on with 1400+ users. Once Captive Portal was turned off, load averages dropped to 0.5.

Load seems higher for Captive Portal when there is significant numbers of users since the transition to pf from ipfw.
