{message}{separator}{throwable with stacktrace}` 59 | 60 | Description of layout: 61 | - date - uses formatter `yyyy-MM-dd'T'HH:mm:ss.SSS` 62 | - level - logging level 63 | - logger - logger full class name 64 | - message - logging message 65 | - separator - new line to separate logging messages 66 | - stacktrace - exception stacktrace 67 | 68 | ### Configuration 69 | 70 | All loggers use synchronous output, **without any async appending mechanism**. 71 | 72 | All loggers are configured to output to *STDERR*. 73 | 74 | Benchmark emulates real world usage of loggers, same way logger will be used in real running application. 75 | To achieve this, benchmark uses real IO output for loggers, but to mitigate IO of the specific machine and console output, 76 | all loggers output is redirected to /dev/null. 77 | This is done to benchmark how loggers are working in real environment including IO interactions and avoid benchmarking how machine prints data to STDOUT where benchmark is running at. 78 | 79 | Loggers have different implementations and such huge performance gaps (as seen by results) occur mostly due to some loggers accessing IO more frequently than others. 80 | So measuring IO interactions is indented and critical to receive real world insights. 81 | 82 | ## Setups 83 | 84 | JMH precaution: 85 | ```text 86 | REMEMBER: The numbers below are just data. To gain reusable insights, you need to follow up on 87 | why the numbers are the way they are. Use profilers (see -prof, -lprof), design factorial 88 | experiments, perform baseline and negative tests that provide experimental control, make sure 89 | the benchmarking environment is safe on JVM/OS/HW level, ask for reviews from the domain experts. 90 | Do not assume the numbers tell you what you want them to tell. 91 | ``` 92 | 93 | ### Setup 1 94 | 95 | This benchmark results are based on run inside **GitHub CI** and **have forwarded stderr to /dev/null**. 96 | 97 | Benchmark setup configuration: 98 | - OS: Ubuntu ([Github CI](https://github.com/GoodforGod/java-logger-benchmark/actions)) 99 | - Processor: Unknown 100 | - Java: JDK 17.0.2, OpenJDK 64-Bit Server VM, 17.0.2+8-LTS 101 | -

case you want to try benchmark yourself, then you should compile and package all benchmarks first: 260 | ```shell 261 | ./gradlew shadowJar 262 | ``` 263 | 264 | Then you can run each of them in their proper directory, for example to run *goodforgod-simple-logger* benchmark: 265 | ```shell 266 | java -jar goodforgod-simple-logger/build/libs/*all.jar 267 | ``` 268 | 269 | If you want to suppress logger output to measure raw performance, you should redirect STRERR that logger produce to /dev/null. 270 | ```shell 271 | java -jar goodforgod-simple-logger/build/libs/*all.jar 2>/dev/null 272 | ``` 273 | 274 | ### Configuration 275 | 276 | You can configure the number of *warmup* and *iterations* with command line arguments, the first argument corresponds to warmups and second is for iterations: 277 | 278 | Example below will run 1 warmup and 2 iteration: 279 | ```shell 280 | java -jar goodforgod-simple-logger/build/libs/*all.jar 1 2 281 | ```
