Could JIT deoptimization be caused by hardware issue?

[星晴]

Hi all,


I have a question about JIT deoptimization behavior in hotspot.


We deployed a Java application on a virtual machine (4 vcpu, 8GB memory).


When analyzing a flame graph, we found that JIT deoptimizations account for about 40% of the cpu samples.


After live migrating this VM to another physical host, the high deoptimization ratio remained unchanged.


Does this indicate that the deoptimization behavior is not related to the underlying hardware?


Thanks for your insights.


Hang Ren.
