The performance optimization skills of the GFC log frame in the Java library

The GFC log framework is an open source framework for recording and managing logs in Java applications.It provides powerful functions and flexibility, but may face performance challenges when processing a large number of log data.In order to optimize the performance of the GFC log framework, we can adopt the following skills. 1. Use appropriate log level: GFC log frame supports multiple logs, ranging from debug to error.In the production environment, the use of appropriate log levels can reduce the number of log records, thereby improving performance.For example, set the log level to INFO or Warn to avoid recording a large amount of debugging information. 2. Use delay calculation: Sometimes, the parameters in the log sentence need to be obtained through complex calculations or I/O operations.In this case, using delay calculations can avoid unnecessary resource consumption.Lambda expression or anonymous internal class can be used to achieve delay calculations.For example: logger.debug("Result: {}", () -> expensiveCalculation()); In the above example, the parameters of the log message will not be calculated immediately, but the calculation is only required when printing the log. 3. Avoid writing redundant data: When recording logs, try to avoid recording redundant information.If the value of a field is the same in the entire log file, it can be extracted into a global variable and cited it in the log sentence.This can reduce the size of the log file and the number of times to write the disk. 4. Asynchronous log records: The GFC log frame supports asynchronous log records, which can be enabled in the configuration file.Use asynchronous records to decide the process of logging with the execution of the application and improve performance.For example: <asyncLogger name="com.example" level="info"> <AppenderRef ref="File"/> </asyncLogger> In the above example, set the logging level to INFO, and output the asynchronous records through the APPENDER named "File". 5. Reasonable configuration log framework: When configured the GFC log framework, reasonably select the appropriate APENDER and layout to meet the needs of the application.Different APENDER and Layout may affect performance.For example, FileAPPENDER may cause performance reduction compared to ConsoleAppEnder because it involves disk writing operations. By adopting the above performance optimization skills, the performance of the GFC log frame in the Java library can be improved to the greatest extent.These techniques are designed to reduce unnecessary logging and improve the efficiency of log records to ensure that the performance of the application is not affected by the log framework.
