CPU
CPU resource consumption can be adversely affected by compression, lockless reads, or a badly designed protections table. In general, there is a trade-off between speed and the number of cores. A minimum of 2.4 GHZ and 8 cores is recommended. With greater speed, fewer cores will do: for example, a 3.2 GHZ and 4-core processor will also work.
