Also, WRR should be reliable for OPS while other schedulers (eg. *LC) are not suitable. > And the traffic routed to each realserver didn't following weight I > set, it's routed pretty much one to one.

"Conns" counter in stats should be according to WRR weights, it shows the scheduler decisions. In your rates listing CPS 0 is confusing, even for OPS. Is it from the new ipvsadm?
