我的问题是如何优化容器以便平均负载恢复正常而不是我现在面临的高负载
答案1
首先，内存和平均负载无关。 花几分钟了解一下区别。
阅读所有链接的参考资料。这很重要。
读完后，这个答案仍然会在这里。
你回来了？好的。
现在，你需要知道的是：高负载不是问题。
性能不佳是一个问题。
崩溃和冻结是一个问题。
磁盘空间不足也是一个问题。
如果你没有真正的问题不要过分关注负载数。
从业务角度来看，负载数越高越好——如果系统运行良好（即没有人抱怨），平均负载为 1000，则说明系统使用效率高。
请注意，我区分了计算效率和业务效率。
如果你是存在实际问题，例如虚拟机性能不佳，平均负载一诊断工具来帮助您排除故障（指示有多少个进程正在等待 CPU）。
您可能无法通过调整虚拟机来优化摆脱这种情况——您的系统对 CPU 的要求超过了它所能完成的工作。平均负载为 300 意味着您有 300 个进程想要使用 CPU（而不管您的系统有多少个核心），这很可能意味着等待时间是显而易见的。
要纠正这种情况，您需要从服务器中移除负载（通过将工作 - 虚拟机 - 迁移到另一个框）。首先迁移“最重”的虚拟机（需要最多 CPU 时间的虚拟机），然后继续移除负载，直到系统性能满足您的需求（无论平均负载如何）。请记住给自己留出一点余地，以防虚拟机工作负载发生变化。
（如果你不是有问题，但就是无法克服高负载数字，这仍然是解决方案 - 移除负载直到数字让您感觉更好。）
