X-agent performance.

X-agent performance.
Dear All, By studying and testing SNMP performance these days, I came up some ideas here, would like to hear your comments: SNMP sub-agent mode slows down the total time of getbulk, by change the SNMP agent architecture from sub-agent to one agent, the performance improves dramatically. See below for some test result, with sub-agent, the getbulk time is approximately 3 times than the time without sub-agent. Table No SubAgent with Sub Agent 16oid, 18 rows 4s 13s 5 oid, 500 rows 38s 140s 70 oid, 70 rows 35s 152s Don’t know if anyone has same puzzle, is there anything wrong here?
