When busy-spining Java thread is bound to physical core, can context switch happen by the reason that new branch in code is reached?

QUESTION

When busy-spining Java thread is bound to physical core, can context switch happen by the reason that new branch in code is reached?

Asked 2020-Nov-01 at 21:20

I am interested in low-latency code and that`s why I tried to configure thread affinity. In particular, it was supposed to help to avoid context switches.

I have configured thread affinity using https://github.com/OpenHFT/Java-Thread-Affinity. I run very simple test code that just spins in a cycle checking a time condition.

A voluntary context switch usually means a thread is waiting for something, e.g. for a lock to become free.

async-profiler can help to find where context switches happen. Here is a command line I used:
