The setting seems not to have any affect (maybe only for TCP
balancing?). Load and drop rate still increases.

Bandwith is at 1,14gbps IN / 194mb/s out, ~160.000pkt/s in/ 100.000pkt/s out
/proc/net/ip_vs_conn: 10832
IPVS Connections (ipvsadm): 10832 (InActConn due to UDP)

Is there any other option to optimize performance/reduce paket drops?
