So we have used www.zenoss.org for many years. Individual collectors are easily handling snmp poll rates of 1.5k oids 
per second(450k per 5m). As zenoss core is open source Its probably worth a look for you.

Subject: SNMP - monitoring large number of devices

Hi all,

recently I have been tasked with a NMS project. The idea is to pool about
20 OID's from 50k cable modems in less then 5 minutes (yes, I know it's a one million OID's). Before you say check out 
some very professional and expensive solutions I would like to know are there any alternatives like open source "snmp 
framework"? To be more descriptive many of you knows how big is the mess with snmp on cable modem. You always first 
perform snmp walk in order to discover interfaces and then read the values for those interfaces. As cable modem can 
bundle more DS channels, one time you can have one and other time you can have N+1 DS channels = interfaces. All in all 
I don't believe that there is something perfect out there when it comes to tracking huge number of cable modems so I 
would like to know is there any "snmp framework" that can be exteded and how did you (or would you) solve this problem.

Thank you.
