Unrealiable RPCs more unreliable than before

In 4.17 unreliable rpcs are often delayed by something like 1 second and calls repeated in short time are often discarded, even if testing locally with 2 viewports in pie.

This can be reproduced in first person template adding a multicast unreliable event as in the following image

and running pie with 2 players. Firing repeatedly from the server, only few shots are replicated on the client.

In 4.16 when testing locally unreliable calls looked undistinguishable from reliable ones. Is this a bug or a feature to save bandwidth? If it is a feature, are there options to make it behave like before?
