The machine in question is using 100% of the cores available. 有问题的机器正在使用100%可用的内核。 In the situation presented, the pc or server has more than 1 core, therefore a process can use more than 1. That's why one process can use 425.7%, meaning that it's using more than 4 cores to do its job.
在这种情况下,个人计算机或服务器具有1个以上的内核,因此一个进程可以使用1个以上。这就是为什么一个进程可以使用425.7%的原因,这意味着它使用4个以上的内核来完成其工作。
