如何知道要调查什么以及如何调查非常慢的存储过程

Blu*_*ppy 2 performance stored-procedures optimization query-performance

我继承了一个又大又慢的存储过程，它给了我一个噩梦：

我不是DBA，虽然我有一些知识，但我不知道从哪里开始识别这个瓶颈。

我的桌面上安装了 SQL Server 2008，并带有生产数据库的精确副本。我正在从 SSMS 运行所有内容，并且尝试过直接使用 SQL 和 SP。SP 与 SQL 的时间足够接近相同，不必担心 - 这是我关心的本地与服务器的时间。

本地:

  • 2GHz 双核
  • 4Gb 内存
  • SQL Server 2008 Sp1
  • Microsoft SQL Server 2008 R2 (SP1) - 10.50.2500.0（英特尔 X86）
  • Windows NT 6.1 上的企业版（内部版本 7601：Service Pack 1）

服务器:

  • 2GHz 双核
  • 4Gb 内存
  • Microsoft SQL Server 2008 (SP1) - 10.0.2573.0 (X64)
  • Windows NT 5.2（内部版本 3790：Service Pack 2）（VM）上的标准版（64 位）

当我“本地”运行时，大约需要10 分钟才能完成。

当我在服务器上运行时，大约需要14 个小时才能完成！！！

[总插入量约 = 14,000,000]

我已经尝试尽可能多地调整 SP 并避免参数嗅探，但不确定为什么这在几乎等效的机器上会慢得多（我知道 SQL Server 版本略有不同，但不明白为什么会这样）有那么大的不同？）

我知道 SP 不是很好，但如果它在本地运行 10 分钟，那么它不是完全的裤子！如果在服务器上花费 60 秒，那仍然可以。

当这些 SP 没有运行时，服务器的负载非常低，而当它们在运行时大约 50% 的 CPU（一个核心 100%？）。本地 CPU 永远不会超过 25%。

我已经分解了 SP，因此它被多次调用，希望可能有所帮助......它在本地完成，但不是很多，但在服务器上没有任何区别。

这绝对是丑陋的 - 您可以删除光标，这将是普遍缓慢的一个重要罪魁祸首，创建一个更加基于集合的解决方案。但这取决于您对重构的一般舒适度，这是否真的是一个好主意。

但是，您可以调查有关服务器的许多事情。

例如 - 服务器上的数据库是否打开了“AutoShrink”？tempdb 是否在特别慢的磁盘上？

您可以比较不同服务器上的执行计划，看看两者之间是否存在巨大差异。使用游标的一个困难是，您最终可能会在早期迭代中制定出一个计划，尽管它对于以后的迭代来说是一个糟糕的计划。但我假设你在两个盒子上有相同的数据，所以这真的不是一个因素。

我会检查服务器上的其他条件，例如磁盘和其他可能正在运行的东西。如果您的文件不断增长和缩小（例如），那么对于在那里运行的任何查询来说，这可能是个坏消息。
