[GitHub] [brpc] cmdmspaint opened a new issue, #2125: 调整bthread_concurrency小于cpu核数不生效问题

cmdmspaint opened a new issue, #2125:
URL: https://github.com/apache/brpc/issues/2125

   用于测试的server是128核的cpu
   brpc内部bthread_concurrency参数的default value应该是9
   ![image](https://user-images.githubusercontent.com/50624748/218966802-2053df34-4bd2-4f2f-b8db-11b131609bdc.png)
   但是为什么在bavr上显示的value是129而不是9呢，这和ServerOptions.num_threads数量默认是cpu core的个数有关吗？
