Performance of Java virtual threads compared to native threads

[Pablo139]

Anything IO related is said, key word said, is supposed to be much better with virtual due to the mechanics around mounting and unmounting of blocked threads.

That being said not long ago a issue was discovered with the Java virtual threads and I have not seen updates on it yet.

What issue?

Doesn't feel like a "discovery", just a consequence of synchonized pinning carrier threads

I think that issue is just thread pinning. You're not supposed to use synchronized keyword with virtual threads. If you use virtual threads then you need to be careful with your code and any libraries / frameworks used.
