Ok, I'll run it again and see if I observe the same behaviour.  It was 
definitely dumpcap which had high memory and cpu usage.

Sorry, I mis-understood what was going on with the dissectors, I thought that 
if I ran the capture through Wireshark the captures would be decoded, I was 
wrong as the raw packets were output to file (obviously).
