Hi Chris, @plummercj
Here are the tests I have conducted:
- tier1, tier2,tier3 all passed
- netbeans with heap usage of 500mb, 1000mb, plus "randomly do some
operation and dump the heap". tested 30 times and all passed.
- a workload that generate different object to fill heap, I have tested
with heap usage from 1GB to 8GB. All passed.
All the scenario are tested with/without the gz option.
Do you think these tests are ok?
BRs,
Lin
