I ran into a similar problem but found that (in my situation) that the SNMP_PING function was the problem. I removed that poller from the poller group and one of my hosts went from a 45 sec poll time to 9. From what I can gather all this does is ping another host from a host via snmp. I didn't need this to happen so I just disabled it. Javier or Craig may be able to shine some more light on that.
But I do also agree that the whole process could stand to be a bit more efficient. I have a machine running right now that monitors SNR, RX and TX signal levels and traffic (~5 snmp values) on about 18,000 cable modems every 5 minutes using a program called Braa. We had issues with it actually sending too many packets over our older linux gateways and using up too many IRQ's and we would see packets drop when the poller when around to the modems off that gateway. Once we got it slowed down we haven't had any issues with it. It would be awesome if JFFNMS could do the same thing. Just a suggestion to better this already awesome software. Keep up the good work!
