The significance totally depends on your application - if it was Voice over IP, it would be unusable.
 
RTT, which is basically the sum of inbound and outbound delay/latency has a number of components. One of these will be the serialisation delay, basically the delay to push all those bits one at a time through the the pipe. Your data rate will impact that. Other delays such as server processing, router hop, queing delay will not be impacted by data rate.

Subject: [Wireshark-users] Shorter RTT

Hi everyone,

I am comparing two captures I did for the same network setup (GPRS dial up) and I notice one capture has a slightly better average RTT, about 0.3s difference. Is this considered a significant value?

Does RTT relates to data rate? What I mean is if I increase the data rate for one capture, will it improve the RTT?

Thanks.
