[0.14.7] Extreme lag when firing guns

[Ilirea]

Every time I start or stop shooting in multiplayer, the game lags out.
This is especially deadly when cleaning up huge biter nests as you can't really tell where your character is at the moment. This leads to me getting stuck and swarmed by tremendous amounts of enemies even with six exosceletons.
This happens not only in vast maps but also in a new test game I started together with a friend.
I don't know if this is a new thing in 0.14.7, but it never happened to me in the 0.13 stable release and my or my freind's internet speed has not changed at all.
Also factorio doesn't even use up all available up- or download speed.
Additional information: My latency is about 40(ms?), but I don't know if this matters.

Because you interact with the world and therefore leave the latency hiding, nothing to get around that.
If you mean the debug display of latency is 40 that would be 40 x 16.7ms so about 670ms which is really bad.

Thanks for your help!
I guess I'll have to live with it...
