Minutes

• Updates

  • Nobody has had the chance to setup YourKit to run tests
  • Test 2 PR discussed, and merged
  • Test 1
    • Nobody has done this one yet
    • On hold given memory issues of running it; large objects take up a lot of memory on the machine running the test
  • Test 2
    • Princeton has run Test 2
    • https://wiki.duraspace.org/display/FF/Princeton+Results+-+Test+2
    • Esmé Cowles thinks he ran Test 3 instead of Test 2 given the size of the files on disk
    • There might be something up with the configuration of Test 2. Not sure it is doing what it is supposed to be doing
    • Need to investigate more what the error that stopped the test was
      • ARJUNA012117: TransactionReaper::check timeout for TX 0:ffff7f000101:ecc1:5737143c:238f73 in state  RUN
        • ActveMQ?
      • Do we continue to give time to investigating LevelDB issues given Modeshape 5 does not support it?

  • Reinstate Test 3, so that the files are above 4KB threshold
  • Test 4 - Summary needed

• Define concrete goals and timeline of this group
  • What type of tests have been run?
  • What are the numbers we're seeing?
  • What are issues that have surfaced?
  • We can pull something together for Test 4?
    • Andrew Woods and Esmé Cowles will take the lead, and Nick Ruest help out editorial-wise
