JMH benchmark for OpenTracing libraries

This repository contains a set of benchmarks to assess the performance of different OpenTracing components and/or libraries. Some tests might include concrete implementations, such as Jaeger and Haystack, mostly for sanity checking purposes.

List of current tests:

Test No Instrumentation Noop Tracer Mock Tracer Jaeger Tracer Haystack Tracer
Throughput, one span, one tag, one log message
Time, one span, one tag, one log message

Code structure

Each benchmark contains common packages to the same purpose:

opentracing-benchmark-spring-cloud
│   
│   
└───io.opentracing.contrib.benchmarks
│   │
│   └───config
│   │   ## Classes to initialize the different tracers
│   │
│   └───main
│   │   ## The class to be executed by JMH 
│   │
│   └───petclinic
│   │   ## Depending on the test, there is one package which contains the example application to be executed by JMH. 
│   │      In this example for opentracing for spring cloud, the official petclinic application is used for the tests.
│   │    
│   Benchmark*.java 
│   ## The different JMH benchmark tests are located in this package
│   │

And depending on the project there are some specific packages, like listeners or servlets, etc.

Properties

This properties can be overrided by system properties:

benchmark.warmup.iterations=5
benchmark.test.iterations=5
benchmark.test.forks=1
benchmark.test.threads=1
benchmark.global.testclassregexpattern=.*Benchmark.*
benchmark.global.resultfileprefix=jmh-

Running it

Run the following command (inside on a specific project)

mvn clean install
java -jar target/benchmarks.jar

Feedback

Performance tests are tricky and we are sure that some things might have done better. We welcome your constructive comments and we appreciate PRs.

Results

We use JMH-visualizer to present the benchmark results. Thanks jzillmann for this amazing tool!.
