Many modern CPUs support some form of hyper-threading that makes multiple virtual CPU cores visible to the operating system when in reality only a single physical CPU core is available. Hyper-threading enables the operating system to schedule multiple tasks concurrently on a single core, and the CPU core will multi-task between the multiple tasks when a task temporarily does not need CPU resources or when it stalls.

Vector makes maximum use of CPU core resources and generally does not benefit from hyper-threading. In fact, the overhead associated with hyper-threading may slow down Vector performance, in which case it is best to disable hyper-threading in the BIOS.
