I use g portal there amazing and you can actually add more ram to your server via more money of course. Yeah thing is ppl build and the more you build the more lag you get. As far as v+ goes that's just a mod right should not cause any lag. I'd try going up on ram for server and keep it around 10 to 15 just my thoughts. I'm sure there is another solution but that's mine. Also I'll join your server friend me.
