A few JMH benchmarks are available to measure performance of some Vert.x sensitive parts.
The benchmarks are executed with biased locking enabled.
The benchmarks configurations a JMH executor that uses VertxThread.
Benchmarks are located in the src/test/benchmarks folder.
Note that these benchmarks have been added to quickly see the impact of changes but do not replace real benchmarking done in a lab.
Package the JMH microbenchmarks
> mvn package -DskipTests -Pbenchmarks
Run them all
> java -jar target/vertx-core-$VERSION-benchmarks.jar
HeadersEncodeBenchmark: encode HttpHeaders- `HeadersContainsBenchmarkv: HttpHeaders contains method
HeadersSetBenchmark: HttpHeaders set method
> java -jar target/vertx-core-$VERSION-benchmarks.jar HeadersEncodeBenchmark
The HttpServerHandlerBenchmark benchmarks the HttpServer that deals with HttpRequest and HttpResponse
objects. It mainly compares a simple hello world application written with Vert.x and Netty.
> java -jar target/vertx-core-$VERSION-benchmarks.jar HttpServerHandlerBenchmark
The RunOnContextBenchmark measures the impact of the disabling thread checks, context timing that are done
when running Vert.x context tasks.
