Hi,
I tried to use LinuxPerfAsmProfiler to view the hottest assembly code,
both -XX:+UnlockDiagnosticVMOptions and -XX:+PrintAssembly we added but I got this output
Hottest code regions (>10,00% "cycles" events):
....[Hottest Region 1]..............................................................................
perf-25250.map, [unknown] (224 bytes)
<no assembly is recorded, native region>
....................................................................................................
48,99% <total for region 1>
....[Hottest Region 2]..............................................................................
perf-25250.map, [unknown] (75 bytes)
<no assembly is recorded, native region>
....................................................................................................
46,55% <total for region 2>
....[Hottest Regions]...............................................................................
48,99% perf-25250.map [unknown] (224 bytes)
46,55% perf-25250.map [unknown] (75 bytes)
0,30% libjvm.so SpinPause (9 bytes)
0,21% kernel [unknown] (0 bytes)
0,15% libjvm.so _ZN22ParallelTaskTerminator17offer_terminationEP20TerminatorTerminator (0 bytes)
I suspect something is missing from my config, but I cannot guess what exactly.
