The reason for this improvement (apart that, in general, it is good to have better performance) is there may be good use case to use a `SimpleProcessor` to emit logs efficiently to standard output. It could be one of the most efficient solutions (from application performance perspective) and thanks to such configuration the user would not lose any logs if the application suddenly crashes. For instance, a useful configuration could be a simple processor with an OTLP file exporter (https://github.com/open-telemetry/opentelemetry-go/issues/5408). I think we might consider changing the following portion of `SimpleProcessor` documentation (but I would prefer to do it as separate PR): > // This Processor is not recommended for production use. The synchronous // nature of this Processor make it good for testing, debugging, or // showing examples of other features, but it can be slow and have a high // computation resource usage overhead. [NewBatchProcessor] is recommended // for production use instead. ``` goos: linux goarch: amd64 pkg: go.opentelemetry.io/otel/sdk/log cpu: Intel(R) Core(TM) i9-10885H CPU @ 2.40GHz │ old.txt │ new.txt │ │ sec/op │ sec/op vs base │ Processor/Simple-16 449.4n ± 7% 156.2n ± 5% -65.25% (p=0.000 n=10) Processor/ModifyTimestampSimple-16 468.0n ± 6% 171.3n ± 15% -63.40% (p=0.000 n=10) Processor/ModifyAttributesSimple-16 515.8n ± 3% 233.2n ± 8% -54.77% (p=0.000 n=10) geomean 476.9n 184.1n -61.40% │ old.txt │ new.txt │ │ B/op │ B/op vs base │ Processor/Simple-16 417.0 ± 0% 0.0 ± 0% -100.00% (p=0.000 n=10) Processor/ModifyTimestampSimple-16 417.0 ± 0% 0.0 ± 0% -100.00% (p=0.000 n=10) Processor/ModifyAttributesSimple-16 465.00 ± 0% 48.00 ± 0% -89.68% (p=0.000 n=10) geomean 432.4 ? ¹ ² ¹ summaries must be >0 to compute geomean ² ratios must be >0 to compute geomean │ old.txt │ new.txt │ │ allocs/op │ allocs/op vs base │ Processor/Simple-16 1.000 ± 0% 0.000 ± 0% -100.00% (p=0.000 n=10) Processor/ModifyTimestampSimple-16 1.000 ± 0% 0.000 ± 0% -100.00% (p=0.000 n=10) Processor/ModifyAttributesSimple-16 2.000 ± 0% 1.000 ± 0% -50.00% (p=0.000 n=10) geomean 1.260 ? ¹ ² ¹ summaries must be >0 to compute geomean ² ratios must be >0 to compute geomean ``` --------- Co-authored-by: Tyler Yahn <MrAlias@users.noreply.github.com> |
