Goals

Initial goals of the Performance and Scalability group:

• Document the current performance of targeted operations in Fedora 4 (creating binaries of various sizes, creating and updating containers)

• Identify performance bottlenecks to inform future development

• Identify performance changes over time with infrastructure updates (e.g., the upgrade to Modeshape 5)

Current Work

• Creating testing scenarios for common operations: Performance and Scalability Test Plans

• Creating small files

• Creating large files

• Creating empty containers

• Creating containers with RDF properties

...

• Running several of the tests by several different institutions, including repeated tests with different storage backends (LevelDB vs. PostgreSQL) or other relevant options:

• Princeton Results - Test 2
  

• Princeton Results - Test 3
  

• Princeton Results - Test 4
  

• UW Madison Results - Test 4
  

• Virginia Tech Results - Test 4
  

• York University Results - Test 4

Future Work

• Have multiple institutions run all of the identified tests with Fedora 4.5.1 to provide a solid baseline measurement of current performance.

• Repeat the same tests with a Modeshape 5 branch to compare performance of the new version of Modeshape.

• Run tests with profiling enabled to gather information most relevant to identifying and addressing performance bottlenecks in Fedora code.
