The rxmonitor hook is called on each received packet. This can get very, very busy as the tx/rx/chanbusy registers are thus read each time a packet is received. Instead, shuffle out the true per-packet processing which is needed and move the rest of the ANI processing into a periodic event which runs every 100ms by default.
