facing delays between every first image generation of new prompt

[Greatz08]

For initial(first) image generation of every new prompt, speed of generation is slow but if we dont change the prompt and just change minor settings like seed,sampler,scheduler then it generates quicker. I thought when models get fully loaded in VRAM+RAM, they will make every image generation quicker (Overall Speed of Image generation is still much much better when compared to vanilla models and methods but i thought to share this behavior with you, so that if there is any fault from my side because of which delay might be happening, then i will try to correct it ).

Btw Image generation is pretty good and i am enjoying it, so thank you very much for this wonderful project mit-han team
