Clarification - does it uses virtual threads under the hood?

[sanjeevirajm]

splitting the operations using tree structure sounds interesting.

i am curious how does that work.

Threads are heavily criticised, because it is bound to system hardware and it's operations are expensive.

In some cases, trying to do operations in parallel using threads decreases performance.

Light weight threads/Virtual threads/Coroutines came after that.

Does bend or the runtime uses something like virtual threads to overcome issues in threads?
