We expect the impact to be low since this is a CPU feature. However, we do plan to conduct performance testing.
This had to be done before the proposal was published for voting.
We are exploring other compatibility mechanisms, particularly for programs that are still single-threaded when they start dlopen'ing. But there is certainly a compatibility cost.
If this results in breaking NVIDIA drivers and other important third-party software, then this is absolutely unacceptable.
