mysql vs mssql performance

Today, database operations are increasingly becoming a performance bottleneck for the entire application, which is especially noticeable for web applications. It's not just about the performance of the database that DBAs need to worry about, it's something that our programmers need to focus on. When we design the database table structure, we need to pay attention to the

Correct compilation methods are important, but they are only part of improving MySQL server performance. Many MySQL server parameters will affect the performance of the server, and we can save these parameters to the configuration file so that these parameters will automatically take effect each time the

MySQL Performance Optimization: Over 20 best experiences sharing bitsCN.com when we design the database table structure and perform database operations (especially the SQL statements used in table queries ), we need to pay attention to the performance of data operations. Here, we will not talk about the optimization of many SQL statements, but only for the databa

received select statement in string mode based on the preset hash algorithm, then, go to the Query Cache to check whether the data has been cached. That is to say, if the select request is already in the cache, the data will be directly returned, thus omitting all subsequent steps (such as SQL statement parsing, optimizer optimization and Data Request to the storage engine), greatly improving performance. Of course, Query Cache also has a fatal defec

MySQL Performance Optimization MySQL supports five different table types, which may be unusual. These five types are BDB, HEAP, ISAM, MERGE, and MyISAM. Among them, the BDB type belongs to one category separately, which is called "transaction-safe", and the other table types belong to the second category, which is called "non-transaction-safe ). The following des

Mysql optimization and mysql Performance Optimization For a data-centric application, the quality of the database directly affects the performance of the program, so the database performance is crucial. I To ensure database efficiency, do the following: ① Database Design ② S

That is, if it is already in the cache, the select request returns the data directly, omitting all subsequent steps (such as parsing of SQL statements, optimizer optimizations, and requesting data to the storage engine), which greatly improves performance. Of course, Query Cache also has a fatal flaw, that is, when any change in the data of a table, will cause all
