Fixed the problem no thanks to the people here, apparently if you turn on "Share usage data" in the EA account settings, it will give you MASSIVE network lag, so turn it off.
absolutely * for me as well, i have 15mbps and everything on every platform loads and works fine, even other games but on the PS4 Battlefront 2 lags like crazy i even get 77ms on the AU server but its still lags (i get 150ms on Hong kong and get near to no lag.) doesnt lag in any other game with the same ping, its also mostly all EA games that do this.
I have the same problems on my PS4 Pro. My internet connection is fine and other multiplayer games like Destiny, Ghost Recon Wildlands, GTA... work perfect. The weird thing is, that I had these issues with other EA games like the first Battlefront or Battlfied 4 too. All this is realy annoying because I actually enjoy playing the game when it works.
