^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 167) a system with only one CPU, say N. If you have a system with more
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 168) than one CPU, say Y.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 170) If you say N here, the kernel will run on uni- and multiprocessor
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 171) machines, but will use only one CPU of a multiprocessor machine. If
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 172) you say Y here, the kernel will run on many, but not all,
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 173) uniprocessor machines. On a uniprocessor machine, the kernel
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 174) will run faster if you say N here.
