I’m attempting to estimate latency between my PC and any servers/clients it interacts with. I don’t want to use Ping for various reasons (requires both ends to allow it, would require additional traffic just to determine latency, etc) and would like to estimate the latency using any TCP ACK RTT measurements.
I started by using Wireshark but I’m finding that the RTT to an IP is significantly lower than the latency reported when I Ping that same destination. (e.g. 55ms TCP ACK RTT vs 168ms Ping)
Am I incorrect in thinking that these values should be similar? Could someone explain what the difference between the two are and hence why the values are drastically different?
