Hi I'm getting massive spike in CPU usage everytime a log is made on reporting between my hotspot and UM routers.

Is there away to cut down the cpu power needed when users are logged into the hotspot? I've noticed that data reporting between the radius server and the hotspot creates a cpu spike with even one user connected - RB450g (hotspot) and RB800 (radius) is creating a 20% spike, when downloading data.
