Maximum Connections Statistics

I need to understand better why MaxConnStats on VIP side is different from MaxConnStats on its Pool side

i think it may be because they are on different side (client-side and server-side).

[root@ve11a:Active:In Sync] config  grep -A 7 ltmVirtualServStatClientMaxConns\ OBJECT-TYPE /usr/share/snmp/mibs/F5-BIGIP-LOCAL-MIB.txt
ltmVirtualServStatClientMaxConns OBJECT-TYPE
        SYNTAX Counter64
        MAX-ACCESS read-only
        STATUS current
        DESCRIPTION
                "The maximum connections from client-side to the specified virtual server."
        ::= { ltmVirtualServStatEntry 10 }

[root@ve11a:Active:In Sync] config  grep -A 7 ltmPoolMemberStatServerMaxConns\ OBJECT-TYPE /usr/share/snmp/mibs/F5-BIGIP-LOCAL-MIB.txt
ltmPoolMemberStatServerMaxConns OBJECT-TYPE
        SYNTAX Counter64
        MAX-ACCESS read-only
        STATUS current
        DESCRIPTION
                "The maximum connections from server-side to the specified pool member."
        ::= { ltmPoolMemberStatEntry 9 }

why there are more connections on "delivery9" node (RoundRobin method).

is delivery9's hardware same as others?
