 If ``N`` is set to 1, an insertion will be performed for every flow. If set to
 0, no insertions will be performed and the EMC will effectively be disabled.
 
+With default ``N`` set to 100, higher megaflow hits will occur initially

+For certain traffic profiles with many parallel flows, it's recommended to set
