sql server performance tuning videos

1.1.1 Summary During the development process, we may encounter system performance bottlenecks from time to time, which may be caused by insufficient code efficiency or hardware or network problems, it may also be a problem with database design. This blog post will introduce some common database performance tuning methods. In addition, to write efficient

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found manyArticleSome of them list hundreds of entries, but you can see that there are a lot of seemingly incorrect or outdated information (which may be applicable to versions earlier than

server| View | index | performance What is an indexed view? For many years, Microsoft®sql Server™ has been providing the ability to create virtual tables, called views. In the past, these views have two main uses: Provides a security mechanism for restricting users to a subset of data in one or more base tables.Provide

disperse the concurrency pressure of the large scale data, also can speed up the speed of special query, the redundant field can reduce the connection of database table effectively and improve the efficiency.3.Design of the primary keyThe primary key is necessary, and the primary key for SQL Server is a unique index, and in practice, we tend to choose the smallest key group to work as the primary key, so t

after you've processed historical data and report data, then add these new hardware, such as faster CPUs and hard drives, larger memory, and so on, but add new hardware postscript to modify your SQL Server configuration to accommodate these new hardware, such as opening/ 3G switch to use more memory. Scale out when scaling the up does isn't suffice or is cost-prohibitive. Use horizontal expansion When yo

, memory, and CPU, Select one of the servers asDatabase ServerWe need to test the performance of each server before. You also need to set some hardware parameters, such as setting disk controller parameters. For more information, see the difference between Writeback and Writethrough. So how to test it? How can we get the test indicators? You can refer to this article:
