Notes

...

• North American User Group
  • 2021-04 Online Fedora Users Group Meeting - American Timezones

...

• Performance testing by Andrey, Peter and Jared
  • Andrey and Jared were seeing fairly bad performance
    • Andrey has performed the same tests on Fedora 4 and 5, and is seeing significantly worse performance on 6
    • Will check to see what the specs of the machine running the tests were
  • Peter and Danny have been unable to reproduce the poor performance
• Including search index commits in same DB commit as the other db commits seems to maintain normal performance
• Search queries are fast except when getting back RDF types. Danny is working on resolving this in a separate PR.
• Comparing POSTs and PUTs - Jared reported that PUTs were a little bit slower
• Single object vs Multi-object transactions
  • At the moment all transactions assume they are multi-object
  • It may reduce the database latency significantly if single object transaction commits were implemented, but at the cost of considerable complexity
  • what percentage of the latency is due to database? To determine how much of a concern this is.
• Calvin testing migration-util with larger heap, checksum turned off
  • Initially faster, slowed back down to 25k per day after about 1.5 million objects
  • Previous runs used about 30% cpu, but not it is only using about 7%
  • It seems to still be processing image files, which are not particularly large
  • UVA originally ran their migration before alpha2, had significantly slower performance in their second migration after alpha2
• Ben C created a ticket to look into slow resumption of migration-util, which iterates back through all the Fedora 3 objects.

...

• Need to follow through on java 11 update and update of integration tests.
• Thomas will take a look at the existing two tickets for updating it

...

• Danny will look at the gh actions PR
• Will update Seth's PR to run gh actions to make sure tests pass
• We will review the unreleased updates to modeshape since the last release was cut, to determine if we want to sync up our fork

...

Actions

•  Look through migration util commits since December to see if there are any potential causes of performance drop off.
