高 CPU 使用率和简单任务负载

高 CPU 使用率和简单任务负载

我知道我的双核根本AMD Athlon 64 X2 5200不强大,但问题是我看到它在空闲时(通常)使用 20% 时的情况,这对我来说不是问题,也许它只是不能做更多的事情...但是,我注意到有时它是“强大的”,但有时却不是。我不知道这是否与包相关、与内核相关或某些服务...但重点是,对于我能完成的最简单的任务,它需要快速达到 80/100%。是的,Firefox 显然会发生这种情况,但浏览我的文件时占用 50/60% 是不正常的。

我注意到这种行为是不正常的,因为我已经看到它在过去或在某些罕见的情况下可以做更多的事情,所以有些事情让我觉得有一个问题导致我的应用程序使用了比应有的更多的 cpu 周期,所有应用程序,也不仅仅是...或者好像我的显卡没有被使用一样。

我从未测试过 Windows 或 MX Linux 19.2 以外的其他系统,因此我无法深入测试它,但是,我有 MX 默认 Linux 内核 4.19,并且我注意到使用 current 时有很小的差异(更好)。

一个过程是曾经比平常消耗更多 CPU 资源的是 Xorg。我不知道这是否正常,因为它一直在 5% 到 15% 之间。但由于我有显卡,我不知道为什么 xorg 需要这个空间,或者它是否受到影响/它会影响其他进程。

我需要为此牺牲我的CPU很多,因为它总是过热,所以在晚上这种影响会稍微减轻一些。

这可能是由于某些内核补丁或错误的库配置而发生的吗? 请索取您需要的任何其他信息。

也许这个 CPU 的冷却出了问题,并且它的速度比平常低了一些?
