10 content recommendations for performance tuning

The performance of a network application is affected by many factors. Database access, file system operations, network bandwidth, and so on are all potential factors. YII has reduced the performance impact of the framework in all aspects. However, there are still many areas in the user's application that can be improved to improve performance. 1. Turning on APC extensions enabling PHP APC extensions can be the simplest way to improve the overall performance of an application. This extension caches and optimizes PHP intermediate code and avoids the time spent parsing PHP scripts for each new request. 2. Disabling debug mode Disabling debug mode is another easy way to improve performance. If the constant yii_debug is set to True, the YII application will run in debug mode. Debugging mode is useful in the development phase, but it affects performance because some components cause additional overhead. For example, the information logger (the message logger) will record additional debugging information for the information being logged. 3. Use yiilite.php when enabling PHP APC

3. Performance Tuning Related

Introduction: 2 database servers, one instance per server, one instance has one library, 2 databases fail each other, and the maximum memory is set to 50% of physical memory, but due to the increase in load caused by the memory shortage problem: In the previous 2000, the database does not respond to the system's memory pressure, So only set 50% to ensure memory balance is used, but

4. Sun will introduce new APIs to tune MySQL performance

Profile: according to Ldquo; Java's father rdquo; James Gosling revealed that Sun will not introduce a new API (application programming Interface) for MySQL database, but it is likely that the M

5. MongoDB Index and Query Analyzer-dex

Summary: Dex introduces MongoDB index and Query Analyzer Dex, a MongoDB performance tuning tool that compares MongoDB log files and index entries and gives index recommendations. Currently, you must provide a URI that connects to the database. Dex only suggests a full index, not a partial index. The Windows platform is not supported. Dex works by Dex in the process of running the main

6. Step through MySQL database Performance tuning

Summary: The speed of an insert query: The time to insert a record is made up of the following: Connection: (3) Send query to server: (2) Analysis query: (2) Insert record: (1 x record size) Insert index: (1 x index) Close: (+) The number here is somewhat proportional to the overall time. This does not take into account the initial cost of opening the table (which is done once for each concurrently running query).

7. Details of SQL Server DBA work

Summary: In a Microsoft SQL Server 2008 system, the database administrator, or DBA, is the most important role in the administration. The DBA's goal is to ensure that the Microsoft SQL Server 2008 system runs properly and efficiently.
