Monks,
I'm working on a utility which issues roughly 100 SNMP get and getTree requests to each of 5000+ servers over a WAN. This is using Net::SNMP on Win32. I need this utility to run as quickly and accurately as possible. Currently, I'm using a couple scripts simultaneously, each using non-blocking requests with callback routines. The whole process is disappointingly slow.. and not very accurate, either. Sometimes the script reports no response from a server, though I can manually issue a request just fine.

Is it possible that since SNMP is based on UDP, there is some data that gets lost in the flurry of packets? Should I limit the number of non-blocking requests I issue in a certain time frame?

Or, should I attack this another way... and use some kind of threading? Does anybody know if Net::SNMP is thread-safe on Win32? Should I just take the plunge and write this in pure C, for speed & threading robustness reasons?
