If there are hundreds of virtual addresses and hundreds of address entries spanning one or more address lists, mcpd might take seconds to reply to a query for virtual address statistics. One of the more commonly visible signs of this is high CPU usage by mcpd if it's processing a large number of queries for virtual address statistics. It is also likely that snmpd responses will be severely delayed to SNMP agent requests.
-- High CPU usage by mcpd. -- SNMP requests/polling timeouts occur because mcpd takes hundreds of milliseconds to respond. Note: If the address lists that contain the entries are not used in traffic-matching-criteria (and therefore do not increase the size of the tmstat virtual_address_stat table), mcpd response time is in the tens of milliseconds.
-- Hundreds of virtual servers. -- Hundreds of address entries spanning one or many address lists. -- Running SNMP queries for virtual address statistics.
