     Re: [snips-users] Snips - RTT Times when monitoring > 1000 devices


I also experienced this problem, it's beacuse there is interpkt delay
between pings. When icmp echo reply comes back, time is counted against
FIRST ping sent in a batch and not against time, when packet to our
destination was sent.

I made just small workaround, that i decreased interpkt delay from 10ms to
1 or 0 ms..
