High Resource usage on 3.0rc7 CPE

I have a 5ghz system using a 532 for the AP and 133c for the cpe. My cpe is running at 30%-40% with frequent forays to 100% when nothing is happening.

The systems in set up as wds station running Nstreem with polling. There is a simple queue to limit band width.

Any one else seeing this Kind of excessive usage with this or similar setups?
