What assumptions are you making about the platform to allow this kind o=

(some ports processed at higher priority)?

This seems like a worst-case scenario. Who would be doing these GetBul=
ks and
why? How often? What are the consequences when the query is not proce=
fast enough?

How good a guarantee is required for this application? No response is
guaranteed over UDP anyway. Is tuning of the snmp server allowed?
