Benchmarks

Benchmarks are based on JMH.

Running Benchmarks

Running benchmarks is disabled by default and can be activated via the benchmarks profile. To run the benchmarks with default settings use.

mvn -P benchmarks clean test

A basic report will be printed to the CLI.

# Run complete. Total time: 00:00:15

Benchmark                                    Mode  Cnt        Score       Error  Units
MappingMongoConverterBenchmark.readObject   thrpt   10  1920157,631 ± 64310,809  ops/s
MappingMongoConverterBenchmark.writeObject  thrpt   10   782732,857 ± 53804,130  ops/s

Running all Benchmarks of a specific class

To run all Benchmarks of a specific class, just provide its simple class name via the benchmark command line argument.

mvn -P benchmarks clean test -D benchmark=MappingMongoConverterBenchmark

Running a single Benchmark

To run a single Benchmark provide its containing class simple name followed by # and the method name via the benchmark command line argument.

mvn -P benchmarks clean test -D benchmark=MappingMongoConverterBenchmark#readObjectWith2Properties

Saving Benchmark Results

A detailed benchmark report is stored in JSON format in the /target/reports/performance directory. To store the report in a different location use the benchmarkReportDir command line argument.

MongoDB

Results can be directly piped to MongoDB by providing a valid Connection String via the publishTo command line argument.

mvn -P benchmarks clean test -D publishTo=mongodb://127.0.0.1:27017

NOTE: If the uri does not explicitly define a database the default spring-data-mongodb-benchmarks is used.

HTTP Endpoint

The benchmark report can also be posted as application/json to an HTTP Endpoint by providing a valid URl via the publishTo command line argument.

mvn -P benchmarks clean test -D publishTo=http://127.0.0.1:8080/capture-benchmarks

Customizing Benchmarks

Following options can be set via command line.

Option	Default Value
warmupIterations	10
warmupTime	1 (seconds)
measurementIterations	10
measurementTime	1 (seconds)
forks	1
benchmarkReportDir	/target/reports/performance (always relative to project root dir)
benchmark	.* (single benchmark via classname#benchmark)
publishTo	[not set] (mongodb-uri or http-endpoint)
