Some delay is normal, as Wes and Thomas have indicated.
But 3s feels a bit excessive, IMO.

If the trap command can work with numeric OIDs,
then you could try turning off the loading of MIB files.

Something like:

MIBS="" snmptrap .....
or
snmptrap -m "" .....

should do the trick.
See if that helps.

Another possibility might be to suppress the reading of config
files. Unfortunately there doesn't seem to be a command-line
option to do this for snmptrap (or the other client-side commands).
But adding the statement:

netsnmp_ds_set_boolean(NETSNMP_DS_LIBRARY_ID,
NETSNMP_DS_LIB_DONT_READ_CONFIGS, 1);

to the code (somewhere before the 'snmp_open()' call would do this.
I've no feel for whether this would make a noticeable difference,
but it's worth a try.
