Так в чём прикол 2-х процессоров? Типо ядра удваиваются (если процы одинаковые)?Да, просто в 2 раза больше ядер. Память еще быстрее, но она вам не нужна.
The biggest limitation with the Minecraft server application is the lack of support for multi-threading. In short, this prevents the Minecraft server from taking advantage of more than a single core of the CPU. Due to this limitation, choosing a CPU with more cores won’t give you any performance benefits or support for additional players. To maximize performance a CPU with a high clock speed and less cores will yield better results than a CPU with a lower clock speed and more cores.
