Make sure the operating system is a 64-bits system, since L2Server won't work in a 32-bits system.
With the "Required" specs you'll be able to get about 300 ~ 500 players with no lag. Anything above that will cause unwanted lag.
With the "Recommended" specs you'll be able to get about 1000 ~ 1500 players with 8GB RAM and with 16GB RAM it should take on 2000 ~ 3000 players without major problems.
