Quick finding

[whynot2024]

Hi! I wanted to report a performance issue I ran into with the Comfyroll nodes.

My ComfyUI output folder had around 24,000 files. With Comfyroll enabled, ComfyUI startup and model refresh (R) were taking several minutes.

After adding timing around /object_info, these nodes stood out:

CR XY From Folder ~99.8s
CR XY Save Grid Image ~101s
CR Output Flow Frames ~101s

After clearing the output folder, ComfyUI startup and refresh became fast again immediately.

It looks like these nodes are scanning the output directory during INPUT_TYPES() / object info generation, so very large output folders can cause a major slowdown.

It may be worth caching the folder contents, avoiding a full scan inside INPUT_TYPES(), or only scanning when the user explicitly requests a refresh.

Happy to provide more logs or test a fix if useful. Thanks for maintaining Comfyroll!
