jprofiler
JProfiler "Recorded Objects" shows different results with/without System.gc even though session settings say to record "Live and GCed objects"
My session settings tell JProfiler to record "Live an GCed objects". I configured the session to start recording "Allocation data" at VM startup. Recording is stopped at VM exit.
When I run my test, "Recorded Objects" shows about 8 mio allocations, 500MB in size. If I add a System.gc() at the end of the test, the "Recorded Objects" drop to 800k allocations, 135MB in size.
Why's that so? I assumed to see the whole object throughput in "Recorded Objects" if I tell JProfiler to record GCed objects as well.
Solution
Switch the "Liveness mode" to "Live and garbage collected objects":
- JProfiler doesn't profile JavaFX embedded in Swing app
- Jprofiler object allocation time is empty, even when "Record object allocation times" is checked
