--v8-pool-size=num

设置 V8 的线程池大小，用于分配后台作业。

¥Set V8's thread pool size which will be used to allocate background jobs.

如果设置为 0，则 Node.js 将根据对并行度的估计来选择合适大小的线程池。

¥If set to 0 then Node.js will choose an appropriate size of the thread pool based on an estimate of the amount of parallelism.

并行度是指在给定的机器上可以同时进行的计算的数量。一般情况下，它与 CPU 数量相同，但在 VM 或容器等环境中可能会有所不同。

¥The amount of parallelism refers to the number of computations that can be carried out simultaneously in a given machine. In general, it's the same as the amount of CPUs, but it may diverge in environments such as VMs or containers.
