database problem

[Moody 0]

my friend has a arma 3 roleplay server, but there is a problem that making this server useless after 70 or more players connected. I mean after 70 or more people connected to play, their character's loading screen being not working, players can't look their garage to spawn their vehicle (takes too much time). We don't know why does it happening and we need to fix this as quick as we can. 

Bottom line:Everything starting to delay in server after 70 or more players connected.

Server's computer system or local servers are very good but i just want to know why is that problem happening please help me

(I'm so sorry about my english)

You know that this here is Exile? I am asking because you speak about garage and roleplay and such. This is not altis life board. Just to be sure: You are using exile? If so: what mods?
