Does that mean they also trade _memory_ for low pause times? Because, in our application, the memory required for avoiding significant GC pauses is at least 4x the amount of memory we actually need at any given time.

This can be significant too.

Have you measured that with ZGC? Because due to using virtual pointers specifically, ”third-party” tools may report higher virtual memory usage than what it actually uses.

It's all about compromises. Only Rust is uncompromised.
