I would turn on debug for active record and see if you can correlated the spikes of the cpu with the backgroundrb call to the db queue since you are using a persistant queue.<br><br>Have a tail of your log file open and another window with top.<br>

I doubt there would be a problem with bdrb. However I would suggest<br>
you to run your program with ruby-prof or use one of the memory<br>
profiles (bleakhouse).<br>
<br>
Try to reduce the case and paste your worker code.<br>
