I disabled it now. Last time I disabled this I noticed the biggest bottleneck was the port module. That takes about 85% of the total time.
That's because ports accounts for 85% of total I/O :)
You can see how much I/O is being caused by running iostat or iotop. You are almost certainly running far more poller processes than your I/O system can sustain.
the fdb-table module is a lot of SNMP due to Cisco being lazy and not implementing a sensible place to get mac address tables from.
You are definitely running too many threads.
