What could be causing slow network updates?

Hello everyone!

I’m currently working on a networked game, and I’m now working on getting all the networking to function properly. Currently the functionality is there, but i got another problem, it seems to be updating very slowly and lagging.

This is for all the movement of the networked actors in the game, they are lagging forward rather that smoothly, while all the un networked actors run perfectly smooth. I’ve changed several settings without any real result, anyone who knows what causes this?
