CAN and RS232 communications are low priority tasks in the processor.
That might explain the serial CAN problems, but we saw them with the 2CAN via Ethernet as well. I think serial CAN tops out at something like 2K pps but the 2CAN jumps that to more like 8K pps from what I understand. At least it's comforting to know that it's not just a 2CAN problem.
