[SNMP4J] using 2 Snmp objecft each with own transport mapping ?

[Guy Katz]

thanks for the reply.
so if my case is an application where a transaction includes executing the
same SNMP command on multiple targets (or even different commands on
different targets). what would you say my best option is regarding increased
performance (in terms of completing all of my synchronous snmp requests in
my transaction) and increased scalability? is it 2 Snmp object each with its
own transport mapping? 2 Snmp object over the same transport mapping with
uncreased UDP buffer?
thanks in advance.

Hi Guy,

By using two different transport mappings you will use two different ports
which will provide two buffers from the OS, one for each port. This will,
of course, provide better scaling. But you can achieve the same by 
increasing
the systems UDP buffer size. Two Snmp instances will also double the number
of threads for receiving responses/requests which will scale better on a
mltu-processor system but not on a single CPU machine.

Best regards,
Frank
