Dotnet Logger Benchmark

Testing the execution efficiency of different Log methods in various versions of .Net, including .Net 5 through .Net 7.

Start with the conclusion

• Use "LoggerMessage.Define<>" Instead of "Logger.Log()".
• Use "LoggerMessageAttribute" Instead of "LoggerMessage.Define<>".

In general, LoggerMessage is the winner all around. As we can see, using LoggerMessage in different .Net versions results in significantly faster execution times, which in turn leads to better performance in the StdDev aspect relative to using Logger Extension.

Moreover, starting from .Net 6, the performance of LoggerMessageAttribute is even better than LoggerMessage.Define<>.
