[SNMP4J] sharing snmp object or not sharing

[Frank Fock]

Hi Sam,

Snmp is synchronized so it can be shared between threads.
By using an instance for each thread, you will triple the
number of threads running (you need to use different
transport mappings and Snmp classes for each thread then).
I doubt that you gain significantly performance by doing so,
but that might depend on your needs and a general answer
cannot be given for that.

Best regards,
Frank
