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

[Frank Fock]

As I wrote, it would depend on the number of processors in your system.
If you have 2 or more CPUs you can increase performance by using 2
or more Snmp objects with a Transport Mapping for each. Sharing
transport mappings is possible but will probably decrease the performance
a little bit.

Best regards,
Frank
