ping behaviour in ros7

Started to move my estate to ros7, there’s a few differences I can get used to, but the most annoying one is with ping

In ros6 I can do “/ping 1.1” and get a response printed a few milliseconds later, if it doesn’t appear practically instantly I know there’s something wrong.

In ros7 it takes a second to output anything, then dumps 2 packets at the same time. It doesn’t look like a reverse DNS lookup, and the packets are emitted and responded instantly. If I press “ctrl-c” output instantly appears.

It’s very disconcerting, are there any settings I can change to stop the output being buffered or whatever is causing the slowness?

If you’re fine with single ping, then run “/ping count=1 1.1.1.1” and you’ll get instant response.
