• Use following VM arg for jdiameter charging server: -Dio.netty.allocator.type=pooled
• Keep seagull client's call-timeout-ms to a reasonable value (machine dependent) e.g. 5 sec
  <define entity="traffic-param" name="call-timeout-ms" value="5000"></define>
• Tune traffic-param also
  <define entity="traffic-param" name="max-simultaneous-calls" value="20000"></define>
