Network: TCP Retransmissions

This statistic shows TCP retransmissions.

When to Check TCP Retransmissions

Rarely. Because packets usually map to protocol operations, it is often more useful to examine these using the Protocol statistics. However, certain network types, as well as client receive buffers sizes, are more prone to TCP retransmissions, which can manifest as high latency.
