Updates
- last met a month ago
- sprater is available to do some work
- elkiss has put in a PR to jmeter
- uploading binary files
- creating test data on-the-fly (100MB/sec)
- suggestion to create test files on disk before ingest
- current approach is creating data in-memory
- jmeter http-sampler appears to load complete file into memory.. this may not scale
- Nick to review PR from elkiss
- awoods to add docs for java_opts and GC tooling
Next steps for testing
- elkiss has large mem machines
- sprater has an 8GB vm ..
...
- maybe get it to 32GB
- elkiss is interested in looking into other tests
- noting that there may be usage patterns of ordering and indirect containers
- next call Mar 14th, second Monday of every month
