我制作了一个同时运行5个线程的程序。这5个线程每个都将运行多个耗时的操作，总共可以持续约3个小时。
在2小时之前，UI似乎运行良好。但是我发现在大约2个小时过去之后，用户界面变得反应迟钝而且滞后。 此外，第5个线程的结果变得错误或具有虚假值。我已经尽力优化我的编码，但这仍然会发生。
我的公司计算机配有i5-6500 CPU和8 GB RAM。我在网上检查过这个CPU一次只能运行4个线程。要运行5个或更多线程，需要一个可以一次运行8个超线程的i7-7700。
我对这个硬件限制是对的吗？或者我可以用C＃编码来解决这个问题吗？仅供参考，我正在使用BackgroundWorker处理我的多线程。
在向老板提议公司必须投资购买新CPU和主板之前，我必须确认这绝对是一个硬件问题。
非常感谢任何建议。 :)

i5-6500有4个硬件线程，这意味着核心的使用得到了splittet并优化为4个线程。您可以在每个CPU上启动任意数量的踏板，但随后它们将运行如下： Singlecore示例：
开始A，停止A，开始b，停止b，再次开始，停止a，starb b 试。
