After compiling  the latest code, it runs much faster, consuming less CPU. Still when I run on a system with a faster performing single thread intel CPU, while using the exact same software and GPU hardware (1080ti) , I get a significant performance  gain. This, plus the fact that nvidia-smi shows less than 50% GPU utilization makes me think that performance could still be improved. Is the JIT being employed transparently or perhaps I need to explicitly tell it to use JIT?
Thank you for the great tool, I love pytorch with its superior debugging and great flexibility!
