Comments:
We need to run benchmark tests to see by how much the speed improved both on CPU and GPU

@patrickvonplaten Can you please help with above comments ?

Hey @punitvara,

At the moment, I sadly don't have the time to handle the big chunk of the PR. It would be great if you could try to:

1) Find a way to benchmark your new function on GPU and show that it yields a speed-up in the forward pass compared to the old function

2) Try out some advanced PyTorch indexing to replace the for loops.

Taking a look at those PRs should help you: https://github.com/huggingface/transformers/pull/9600, https://github.com/huggingface/transformers/pull/9453, https://github.com/huggingface/transformers/pull/6064

Closing due to inactivity. Sorry @punitvara, I saw a lot of interest from other people to open a PR and this one seems to have stalled. Feel free to re-open it and give it a second shot if you want :-) 

I got busy into some other work. I will try to work on different issue. If you get any PR, feel free to merge it
