有好幾種:編譯和重新編譯 SQL 陳述式、遺失索引、多執行緒作業、磁碟瓶頸、記憶體瓶頸、例行維護以及解壓縮、轉換和載入 (ETL) 活動等等。使用 CPU 本身並沒有錯 — 執行工作本來就是 CPU 的職責所在。而良好的 CPU 使用率的關鍵就在確保 CPU 處理的是您要它處理的任務,而非把運算浪費在缺乏最佳化的程式碼...
的因素有很多:SQL 语句的编译和重新编译、缺少索引、多线程操作、磁盘瓶颈、内存瓶颈、日常维护以及抽取、转换和装载 (ETL) 活动和其他因素。利用 CPU 本身并不是一件坏事情,执行任务是 CPU 的职责所在。CPU 利用率正常的关键是确保 CPU 处理您需要它处理的任务,而不是将循环浪费在不良优化的代码或缓慢的硬件上...
