Minutes

Topics on Fedora Performance/Scaling

• Nick - none
• Colin - mocking large-scale tests, alt-methods of doing that
  • desire to test multi-TB loads
• Kieran - interested in testing processes and procedures
  • are both Tomcat and Jetty tested? - mostly Tomcat
• Kevin - interested in validating release candidates
  • now more generally interested in loading issues
  • multi-threading topics
• Danny - interested in scaling as it relates to HyBox
  • "many members" issue
  • multi-tenant support
    • Colin has done this in Hydra... but has not been able to backup single hierarchies
    • using different base-containers
• Yinlin - interested in large files

2016 work summary

• Are the defined tests adequate for the interests above?
  • Challenge in have a test environment that has enough disk space
  • Maybe use OpenSSH:rand to mock many files
  • Is running this on AWS infrastructure a possibility?
    • Who is going to pay for a 20-TB EBS volume?
    • Performant disk i/o can be expensive in AWS
    • AWS tests should include data around size/time/cost of previous tests
• We need to summarize the results of 2016 testing
  • Colin available to help in the visualization of the previous test results
  • Yinlin has created graphs of his tests
  • Colin has modified scripts based on team feedback
• Yinlin - need to write report for each test
• Interest in maintaining results in a GitHub
  • ACTION: create results repo in fcrepo4-labs
  • ACTION: write a report from last year's results
    • Current reports do not provide immediate clarity of the state of Fedora
  • Volunteers:
    • Colin to work on scripts - fcrepo4-labs
    • Nick/Yinlin to work on drafting - will use GitHub
    • Colin to generate R-Script outputs that can be starting point for summary doc
    • Data result locations: post to S3

Actions

• Colin Gross to transfer fcrepo_perf_analysis to fcrepo4-labs
• Andrew Woods to post test outputs to S3
  
• Colin Gross to push outputs from R-scripts to GitHub
  
• Nick Ruest and Yinlin Chen to take above R-script output as starting point for performance test summary report
