Hardware upgrade is not an option seeing as we run on the best hardware on the market

CPU: E3-1245v2 3.8ghz
RAM: High speed 1800mhz 32GB
HDD: Raid 0&1 10k RPM HDD's.
Port speed: 1 Gbit
Internet speed: 200mbit down and up

That being said, we are working on some lag improvements on the server and we are soon moving to a new box that is better for eu pings.
