Benchmarks

There are six main configurations::

  1. Logger from Microsoft.Extensions.Logging.Abstractions package (default)
  2. Source generator from Microsoft.Extensions.Logging.Abstractions package (default-gen)
  3. Logger from Microsoft.Extensions.Telemetry.Abstractions package (telemetry)
  4. Source generator from Microsoft.Extensions.Telemetry.Abstractions package (telemetry-gen)
  5. Source generator from AutoLoggerMessage package (auto-gen)
  6. Source generator from AutoLoggerMessage package with Microsoft.Extensions.Logging.Abstractions installed (auto-telemetry-gen)

Logging without any parameters

Configuration Mean Allocated
default-gen 12.35 ns -
telemetry 19.46 ns -
default 23.12 ns -
auto-gen 27.41 ns -
telemetry-gen 28.32 ns -
auto-telemetry-gen 33.97 ns -

Conclusion: for logging without parameters, the difference is minimal

Logging up to 6 parameters

Configuration Mean Allocated
auto-gen 14.80 ns -
default-gen 25.88 ns -
auto-telemetry-gen 85.30 ns 144 B
telemetry-gen 87.11 ns 144 B
default 99.18 ns 216 B
telemetry 107.33 ns 216 B

Conclusion: when parameters are provided, source generators outperform the other configurations in terms of execution time and memory usage. The AutoLoggerMessage source generator adds minimal overhead.

Logging with 7+ parameters

Configuration Mean Allocated
default-gen 20.31 ns -
telemetry-gen 92.35 ns 168 B
default 107.50 ns 248 B
auto-telemetry-gen 110.17 ns 248 B
auto-gen 112.47 ns 248 B
telemetry 122.10 ns 248 B

Conclusion: due to a limitation, we fall back to the original implementation. The results are similar, but default-gen configuration still uses an optimized version as it packs these parameters into a structure. Something to address in the next release, as the usage of six or more parameters usually is quite low.

Logging complex objects

Configuration Mean Allocated
auto-gen 18.00 ns -
default-gen 26.40 ns -
telemetry-gen 46.82 ns -
auto-telemetry-gen 48.29 ns -
default 71.62 ns 72 B
telemetry 77.28 ns 72 B

Conclusion: for logging complex objects with a tree-like structure, we observe that source generators do not allocate memory and yield faster results.

Logging complex objects with [LogProperties] enabled

Configuration Mean Rank Allocated
telemetry-gen 680.60 ns 1 144 B
auto-telemetry-gen 683.07 ns 1 144 B

Conclusion: results are about the same.
