Remove System.debugs

System.debugs statements are a straightforward way to debug our Apex code, but...

Did you know that System.debug can significantly affect Apex code performance?

System.debug('Here');
System.debug('My Debug');
System.debug('Account ==> ' + acc);

Debugs that contain complex data types have the most significant impact on performance. Values need to be converted to a String to pass them as parameters to System.debug.

If there is no specific reason to keep debugs in your code, you should always remove them!
