Performance Problems

The RTT column of the Performance section of the PathPing output might identify a performance problem. This column shows round-trip time (RTT) in milliseconds, which is the two-way latency of communications with that particular device. Although all networks will show gradually increasing latency as the hop count increases, a large latency increase from one hop to the next identifies performance problems.

Performance problems might also be evident from a high percentage shown in the Lost/Sent = Pct column. This column measures packet loss. Although packet loss in the single digits generally does not indicate a problem that would cause performance or connectivity problems, packet loss of greater than 30 percent generally indicates that the network node is experiencing problems.

Note If a network device shows packet loss of 100 percent but packets are processed at later hops, the network device has been configured to not answer PathPing queries, which does not necessarily indicate a problem.
