Java Agent Performance Tests

Integration level performance tests for the Java Agent.

Perf Script Dependencies

run-perf-test.sh requires the following (available on homebrew or a linux package manager):

bash (>=4.0)
wrk
nc

Running a Test

Build the shadow jar or the distribution zip for the server you wish to test against.
Run the performance test script passing in the agent jars you wish to test.
(optional) Save test results csv and ponder the great mysteries of performance optimization.

Example

Jetty

./gradlew java-agent:benchmark-integration:jetty-perftest:shadowJar
# Compare a baseline (no agent) to the 0.18.0 and 0.19.0 releases.
/usr/local/bin/bash ./run-perf-test.sh jar jetty-perftest/build/libs/jetty-perftest-*-all.jar NoAgent ~/Downloads/dd-java-agent-0.18.0.jar ~/Downloads/dd-java-agent-0.19.0.jar
cp /tmp/perf_results.csv ~/somewhere_else/

Play

./gradlew :java-agent:benchmark-integration:play-perftest:dist
# Compare a baseline (no agent) to the 0.18.0 and 0.19.0 releases.
/usr/local/bin/bash ./run-perf-test.sh play-zip play-perftest/build/distributions/playBinary NoAgent ~/Downloads/dd-java-agent-0.18.0.jar ~/Downloads/dd-java-agent-0.19.0.jar
