net_mdm_client_send_every = 3
net_mdm_server_send_every = 3
This will do for any client. When you set them to 2, the client must be able

As for the race. I believe the race is ended when there are no cars left. So
if you leave out the AI cars, the server should never be in a race for a
long time when no one has connected.
