在多个路由中声明的workerpool是否仍然可以保持其cpu使用率而不关心阈值

Question

我希望找到一个带有workerpool的node.js系统来处理CPU密集型任务，但是 对于多条路由中的 cpu 使用情况，我有些困惑。 一个场景是这样的：

route1.js:
  const workerpool = require('workerpool');
  const pool = workerpool.pool(__dirname + '/job1.js');
  pool.exec.......
route2.js:
  const workerpool = require('workerpool');
  const pool = workerpool.pool(__dirname + '/job2.js');
  pool.exec.......
route3.js:
  const workerpool = require('workerpool');
  const pool = workerpool.pool(__dirname + '/job3.js');
  pool.exec.......

当node.js使用这三个文件时，它们会创建自己的workerpool，并且 由于worker_thread号及其控制是通过node.js内部实现的，这是否可能 创建门槛问题？以及如何正确使用workerpool，非常感谢。

Answer 2

我要做的就是只有一组工人。 Worker 可以公开多个函数，因此您的 Worker 可以毫无问题地公开 job1、job2 和 job3。如果您为每个池创建一个池，则需要考虑池可能会相互冲突......

考虑您的池获得 100% 的 CPU，这意味着如果所有 3 个池都已满，您最多可以需要 300% 的可用资源。

如果您为它们分别分配了 33%，这意味着您最多可以要求 100%，这很好，但如果一次只有 job1 被大量需要，它将只能使用 33% 的可用资源。

通过使用单个池，您可以达到 100%，而无需超过 100% 的可用空间。
