How to optimize the system, make the computer faster,
Binary: 0 | 1
1, CPU affinity is the central processor affinity
2. Start a new program

The specific explanation: uses the system to carry on the reasonable allocation to the CPU resources, for example arbitrarily opens the computer on any thing to use the CPU core to make the call, this too takes the resources
So we have to use the system to control the kernel, to open anything on the computer, such as we open a Notepad computer is four cores 0, 1, 2, 3. We want to use 0 and 1.
If the kernel is running on Notepad, the 0 and 1 cores correspond to 1, 1. The 2 and 3 cores correspond to 0 and 0 (we use binary here) so kernel 0123 corresponds to binary
0011 (from right to left to correspond), with 0011来 multiplied by 2 of the second square and 0x2 3 +0x2 of the 2 square +1x2 1 Times Square +1x2 0. The results can be used start/affinity 3 Notepad
Command-to-notepad control of the kernel (3 is 0011 of the 2-time result)

If hexadecimal, that is: start/affinity 0xf notepad (f is hexadecimal)

Binary: 0 | 1
---------------------
      per available range     range
