The NWLink SPX performance object consists of counters that measure data transmission and session connections for computers using the SPX protocol.
Datagrams/sec
Datagrams/sec is the rate at which datagrams are processed by the computer. This counter displays the sum of datagrams sent and datagrams received. A datagram is a connectionless packet whose delivery to a remote is not guaranteed.

Counter Type: PERF_COUNTER_COUNTER
Datagram Bytes/sec
Datagram Bytes/sec is the rate at which datagram bytes are processed by the computer. This counter is the sum of datagram bytes that are sent as well as received. A datagram is a connectionless packet whose delivery to a remote is not guaranteed.

Piggyback Ack Timeouts
Piggyback Ack Timeouts is the number of times that a piggyback acknowledgment could not be sent because there was no outgoing packet to the remote on which to piggyback. A piggyback ack is an acknowledgment to a received packet that is sent along in an outgoing data packet to the remote computer. If no outgoing packet is sent within the time-out period, then an ack packet is sent and this counter is incremented.
