1. you should try wlc ( weighted least connection ) - probably in your
case it should perform better
2. why do you use "persistent" parameter ? is there any special purpose
for that ? if not - you should remove it.
and one more thing - use ipvsadm to monitor your connections - you can
get the LVS connection table using ipvsadm as well
cheers,
