Forge BE question - switching between models

Nobody has claimed this yet.

Hi all. I'm not sure this is an issue, but the thing I've noticed is that loading of models (switching between them) is what's taking most of the time for me during image generation. I'm using the same model (checkpoint), same ClipSkip. But this model are loaded all the time, multiple times during generation, each generation.
Is there a way to avoid that ? I mean I don't change models, why system is loading them each time from the scratch ? wtf ?

Example of 1 banch of model swtiching (have them during 1 image generation)

The report names no files, tests, or entry points; begin by reproducing the repeated SDXLClipModel, SDXL, and AutoencoderKL loads from the provided log. Trace the model-loading path and verify that repeated generation with the same checkpoint no longer reloads unchanged models.
