前面直接上结论：
如果有超线程，则设置核心数为物理核数量；如果没超线程，则设置为物理核数量-1.
昨天的波兰 i7杜甫开通，CPU i7-4790，支持 AES。测试了下 hash 速度与配置核心数的关系，得到下面的数据：
8core 262
7core 272
6core 255
5core 269
4core 306
3core 244
2core 168
1core 83
可以看到设置的核心数在4的时候收益最大，而4也刚好是 i7-4790 的物理核心数 https://ark.intel.com/products/80806/Intel-Core-i7-4790-Processor-8M-Cache-up-to-4_00-GHz 。看 xmr 配置说明也是这么说：
Note that on hyperthreading systems it is better to assign threads to physical cores.
