You can save memory/cycles by disabling conntrack for
the IPVS traffic. Try such rules and report if there is any gain:
# Remote clients:
iptables -t raw -A PREROUTING -p tcp -d VIP --dport VPORT -j CT --notrack
# If using local clients to VIP:VPORT:
iptables -t raw -A OUTPUT -o lo -p tcp -d VIP --dport VPORT -j CT --notrack
You will not be able to match by RELATED,ESTABLISHED but
-m state --state UNTRACKED should work, if needed at all.
