> I did some experiments with the lra testing and normally tests pass on my laptop. But as you mentioned it's probably timing issue as when I slow down the network (I used tc as described at [1]) then the tests started to fail[2] (I'm on master branch).
> Do you think you can check it on your laptop if you can see the same issue? Or how to manage that?
