Hi Kevin, please follow the thread "Controller performance: high cpu load", in which I describe a similar situation I observed with a RAIDb1 config and Emmannuel gave me many replies to check my configuration. If you follow those steps and still have a slowdown, I'd like to know if you experience an high cpu load on the controller node. By the way, I've just tried the new 2.10.10 release and the high cpu load still persists, but I've observed a slight performance improvement (from 1200txn/s to 1400txn/s).
