[Problems with mission (lag) :/]

Guys I did the mission with more or less 60 AI and 4 scripts ... worked great scripts, everything worked, but when my friend comes on my server I can't see him walking, it gets stopped her, and when he tries to kill any enemy cannot, it is as if he were a spectator ... does it have much AI in game and have to wait for "take the lag"?
