[SNMP4J] 1 sec to send a pdu with SnmpRequest

[PHIL BERGSTRESSER]

Jason,
    I would predict that the delay is in the agent responsiveness. The
way you evaluate that is to put a sniffer on the wire that reports
message traffic and timestamps and then you will have clear evidence of
the responsiveness of the agent. 
    If you are running your test routines on a Solaris based system,
there is a built in program named snoop that will trace the ethernet
interface out and into your machine with timestamps, and protocol
interpretation along with the hex packet dump. If on MS Windows,
download the free Ethereal packet sniffer. This presumes you are using
Ethernet as your interface. 
    UDP or TCP packets can be isolated by protocol so you don't have to
look at other network traffic, but you want to run wide open at first to
see if there are other messages that are consuming bandwidth that might
be interfering.
    HTH,
Phil
