That worked as far as functionality is concerned, but timing didn't improved. Its more or less same.

 The API and the OS will handle that, no problem.

But I need to send 500 parallel queries to 500 different devices. If there is no separate port for each instance, how will the response from devices be processed?

 Hi 
You are binding a new port with any new Snmp instance. That's a big performance overhead that is not needed. Simply use a single Snmp instance instead.
