Testing utility for measuring performance of various ways of modeling/persisting PREMIS event logs within a Fcrepo4 repository

Creation of objects and events are implemented using Java based clients to accurately represent performance of serialization and clients within a java based repository application.

Tests are coordinated with shell scripts for ease of use and to keep the fcrepo JVM separate from the test execution.

For more information using the java testing utility:

1. build the project mvn install
2. then run java -jar target/premistest-0.0.1.jar -h

Setup Batch Tests

1. Download fcrepo 4.7.3 jetty console and place it into the downloads directory: https://github.com/fcrepo4/fcrepo4/releases/download/fcrepo-4.7.3/fcrepo-webapp-4.7.3-jetty-console.jar
2. Run test scripts located in the bin directory. To perform, run: bin/perform\_test_50k.sh bin/perform\_tests_num_events.sh or create a new script based off of those.

Methodology:

• Jetty restarted between most tests to avoid performance degradation
• Data within fedora deleted during restart unless specified otherwise
