Also 15.2 releases have issues with ipsec mib it will increase incrementally number of ipsec tunnels so every poll will be larger and larged. When mine hit about 1500 tunnels snmp polling about 12mb of data.

I had this same issue with one of my ISR 891 routers. Polling the vlan interfaces took ages compared to all the other 891s. This one slow device had a different IOS revision. Updated to match the "faster" routers and the issue went away.
15.0(1)M4 was the slow IOS, 15.1(4)M6 is much faster.

That is a very helpful solution. Running the debug command on a 3750 stack, it didn't seem to hang on one specific command, it just seemed to run very slow on gathering information per port. I'm inclined to say that it's a problem on the 3750, we're using SNMPv3 with authPriv.
I'll throw TAC the question and see if they know why return information from the snmpbulkwalk is taking forever. I'm just trying to eliminate the server or the local MySQL DB from being the issue.

Have you run the poller in debug mode to see what commands it is hanging on? I just tested our largest 3750 stack (796 ports, 8 sensors) and it finished in 37 seconds one time and 96 seconds another time. It is possible that the longer time conflicted with a production poller or that something else was happening on the switch. If you can find one command that is causing the hang up you can open a TAC case with Cisco to find out why the switch is slow.

Yes we have the same issue on some of our Cisco devices, we pulled them out of the list for now. I would like to know how to fix this issue.

Is anyone else having huge response times in their polling of a Cisco 3750 stack?
I?ve increased the number of pollers I have to something close to 17, but my 3750s seem to take forever to respond (anywhere between 200 ? 999.99+ seconds). It may be an issue on my 3750s, but my polling intervals on my devices is several hours.
I have 2950s and 6509s that don?t seem to have any issue responding in a short amount of time (<20 seconds).
