首先，記憶體與平均負載無關。 花幾分鐘時間閱讀其中的差異。
閱讀所有連結的參考資料。這一點很重要。
當你完成後，這個答案仍然會在這裡。
你回來了？好的好的。
現在，您需要知道的是：高負載不是問題。
性能差是個問題。
崩潰和凍結是一個問題。
磁碟空間不足是一個問題。
如果您沒有實際問題，請不要擔心負載數量。
從業務的角度來看，負載數越高越好——如果系統執行良好（即沒有人抱怨），平均負載為 1000，那麼您就可以有效地利用系統。
請注意，從業務的角度來看，我在計算高效和高效之間進行了區分。
如果您遇到實際問題，例如 VM 性能不佳，負載平均是一種診斷工具，可幫助您解決問題（指示有多少程序正在等待 CPU）。
您可能無法通過調整 VM 來優化擺脫這種情況的方法——您的系統要求 CPU 做的工作比它所能做的要多。平均負載 300 意味著您有 300 個程序想要使用 CPU（相對於您的系統有多少核心），這很可能意味著等待時間很明顯。
要糾正這種情況，您需要從伺服器上移除負載（通過將工作 - 虛擬機 - 遷移到另一個盒子）。首先遷移“最重”的虛擬機（需要最多 CPU 時間的虛擬機），然後繼續移除負載，直到系統性能滿足您的需求（不管平均負載如何）。請記住給自己留一點空間，以防 VM 工作負載發生變化。
（就此而言，如果您沒有遇到問題，但無法克服高負載數字，這仍然是解決方案 - 移除負載，直到數字讓您感覺更好。）
