javascript - 限制 Web Worker CPU 利用率？

Question

我正在考虑使用 Web Workers 编写一个长时间运行的 CPU 密集型操作，并且似乎可以使用这些将客户端的 CPU 推到 100%。（请参阅Web Workers 能否利用 100% 的多核 CPU？）

有谁知道任何有效的方法来限制网络工作者的 CPU 利用率？

Answer 1

Indeed there is a way.

Structure your computations so they can be done by repeatedly calling a function which performs a part of the work before exiting. Just before exiting, use setTimeout to schedule a new call on the worker function in a few milliseconds. The wait time can be adjusted to use nore or less CPU time.

function doWork () {
  var timer = new Date ();

 // do n cyles of work here


 timer = new Date () - timer; // time spent working 
 setTimeout (doWork, timer);  // wait an equivalent time for 50% processor load
}
