How speed up the " check images " step ?

[BenDes21]

Hi there, currently training a realistic SDXL checkpoint with a dataset of 85 000 HD images. Im currently using dreambooth Kohya_ss with an A100 80vram from runpod.

The thing is that the preliminary step where kohya_ss " check the images " taking too long time ( around 12 hours for my whole dataset and this is not even the training of the dataset yet ). :

Rent an a100 is a bit costly so Im wondering if there is a way to speed up this process and if yes, which kohya_ss setting will allow me to do that or at least SAVE this step for the next trainings. Thanks
