    Solaris 10 UDP kstat counters

    jess
      What is the difference between ip_udp_fast_path and ip_udp_slow_path? Also, does anyone know a way to see the amount of UDP buffer in use?

      Thanks.

          It's fast if the incoming packet gets a hit in the packet classifier (e.g. we have
          bound endpoint which matches port, address) and we can immediately find the correct
          conn_t to handle the packet.

          It's slow if we have to look harder for the conn_t to deliver the packet.

          This may seem a little bit vague but this is implementation specific with conditions
          that are subject to change.
