Performance Impact for the Application when using ADFLogger

Question

Hi All,
I am very new to ADFLogger and I am going to implement this in my Application. I go through Duncan Mill's acticles and got the basic understanding.
I have some questions to be clear.
Is there any Performance Impact when using ADFLogger to slower the Appllication.
Is there any Best Practices to follow with ADFLogger to minimize the negative impact(if exists).
Thanks
Dk

Well, add a call to a logger is a method call. So if you add a log message for every line of code, you'll see an impact.
You can implement it in a way that you only write the log messages if the log level if set to a level which your logger writes (or lower). In this case the impact is like having an if statement, and a method call if the if statement returns true.
After this theory here is my personal finding, as I use ADFLogger quite a lot. In production systems you turn the log lever to WARNING or higher so you will not see many log messages in the log. Only when a problem is reported you set the log level to a lower value to get more output.
I normally use the 'check log level before logging a message' and the 'just print the message' combined. When I know that a message is printed very often, I first check the level. If I assume or know that a message is only logged seldom, I just log it.
I personally have not seen a negative impact this way.
