对于像这样的受cpu限制的工作量，拥有比cpu多的线程(或执行组)将导致收益递减。

For a CPU-bound workload such as this one, having more threads (or execution groups) than CPUs leads to diminishing returns.

至此，您的边际收益将开始逐渐递减，因为进一步增加堆大小将不会带来成比例的性能改进。

At this point, you reach a point of diminishing marginal returns where increasing the heap size further does not yield a proportional performance benefit.

这个例程将遍历tcp控制块表，并且对每个连接的超时(以计时单元为单位进行指定)进行递减操作，即每次减一。

This routine walks through the table of TCP control blocks and, for each connection, it decrements the timeout, specified in ticks, by one.
