Which logging framework is best for Java?

class); public ReturnType myMethod(Param p, Param2 p2) { …. …. try { .. } catch(MyException e) { logger. log(“Exceptions happen!”, e); //this will put all the details in log file configured earlier } …. } …. }
Which is better Log4j2 or Logback?
File appender As in our first test, Logback performed faster in both synchronous and asynchronous logging when compared to Log4j 2 and JUL. With synchronous appenders, the difference between Logback and Log4j 2 is almost imperceptible. However, the difference between Logback and JUL is an incredible 11.68 seconds!
Is Log4j asynchronous?
Asynchronous Loggers are a new addition in Log4j 2. Their aim is to return from the call to Logger. log to the application as soon as possible. You can choose between making all Loggers asynchronous or using a mixture of synchronous and asynchronous Loggers.

How does multithreaded logging improve application performance?
This is due to natural pauses between case execution. Despite fast M.2 SSD, multithreaded logging improve performance by the multiple times. If your application writes on the HDD or on the virtualized environment then difference will be much bigger.
How to make logging more effective in C #?
There are two practices that will help make logging more effective: logging context and structured logging. Logging context means adding the “Ws” to log entries.
