If i put32 slots my server work so good and 0 lag… but if i put 64 slots on mi server when we are 40/50 all get 1200ms ping and get a lot of bugs (cant delete vehicles, lag etc…) why this? I have good machine on ohv…

Because 64 slots server requires you to modify your server scripts. On default their values are of a 32 slot server. Also its know to be buggy and its up to you to make it work properly until they release it fully.

Seemingly you don’t, or you’re running broken/inefficient scripts.

I dont know why is this…
