LoggingBenchDemo

Benchmarking ways of logging messages with or without arguments

In this demo, i m using BenchmarkDotNet library in order to benchmark various ways of logging messages with or without arguments.

1️⃣ DefaultLoggerBench : a bench based on default logger provided by microsoft

2️⃣ DefaultLoggerVariantBench : a bench based on a custom wrapper around default logger

3️⃣ SerilogLoggerBench : a bench based on a default logger configured with serilog logger

4️⃣ SerilogLoggerVariantBench : a bench based directly on serilog logger

In order to run benchmarks, type this command in your favorite terminal :

✍️ .\App.exe --filter *DefaultLoggerBench*

✍️ .\App.exe --filter *DefaultLoggerVariantBench*

✍️ .\App.exe --filter *SerilogLoggerBench*

✍️ .\App.exe --filter *SerilogLoggerVariantBench*

As you can see, the default logger is not optimized unless you use IsEnabled, Define or LoggerMessage in order to eliminates the issue of object[] allocation and unnecessary calculations.
