This benchmarking module is provided for maintainers, allowing them to check that their changes have not degraded performance. It uses the Java microbenchmarking harness, JMH.
The benchmark test measures the time taken to track one event. Note that this does not include the time for the event to be processed and sent, which happens asynchronously.
To run the test, navigate to this folder and run:
$ ./gradlew build
$ ./gradlew jmhThe tracker version is set in the build.gradle file. Change the specified version to benchmark a different tracker version.
dependencies {
jmh 'com.snowplowanalytics:snowplow-java-tracker:0.11.0'
}Note that you may also need to edit the TrackerBenchmark closeThreads() code. Versions from 0.12.0 onwards must call a different method. This is explained in in-line comments.
