I would like to consult the multi-process Cook CPU performance issues, in the use of the default single-process mode COOK, CPU performance is basically 100% , but the use of multi-process such as 3 process, well, after the CPU is used 100% , it will decline, it will stabilize at, say, 90% of this stage, and then until the end, it will not be able to run full performance. why?
