Not sure what caused this, but in the new release it may perform better. Some easy-to-stuck packages are removed.

You were right!
There's a performance regression in PyTorch 2.5:

PyTorch 2.6 nightly seems not improving this (for now):

Maybe stay at PyTorch 2.3/2.4 for a while for max performance?

Maybe install on Linux WSL2 will perform better?

@Falkonar If not using 3D-Pack, it's OK and performing well. But 3D-Pack is not working on WSL2. YanWenKun/ComfyUI-Docker#73
