, the memory occupied by SQL Server can be roughly estimated using this formula: Memory occupied by the buffer pool + Page occupied by the buffer pool + non-buffer pool memory allocated by multiPageAllocator, 9.

connection data packet is 4 kb, unless the client is specially set to exceed 8 KB (not recommended)Third-party CODE memory applications are generally applied in stolen mode. For example, the CLR may apply in reserved/commit mode.Each thread's memory is applied in MB format, and is naturally stored in memtoleave.The reason why I spent so much time talking about the memory classification of SQL Server is tha

Recently, due to work needs, I hope to make a comprehensive summary of the considerations related to SQL Server database performance optimization. After searching online, I found manyArticleSome of them list hundreds of entries, but you can see that there are a lot of seemingly incorrect or outdated information (which may be applicable to versions earlier than SQL
