recommended number of fine-tuning samples & batch size?

[nihirv]

I've read through multiple issues here which mention that fine-tuning requires a large batch size. By virtue of this, I imagine it also requires a good few number of fine-tuning examples.

Could someone provide a rule of thumb of what we should be looking at for the number of fine-tuning examples and batch size? Is default batch size of 128 enough? Or should we be going higher
