## ComfyUI slowdown may be caused by models being reloaded from disk A Reddit post collects several open GitHub issues in **ComfyUI** and related repos, warning that slower generation times may not be a hardware or workflow problem. Multiple users report models being reloaded from disk instead of staying in RAM or cache. The post links to issues across **Comfy-Org/comfy-aimdo**, **ComfyUI**, and **ComfyUI-GGUF**, suggesting the slowdown is a real and recurring infra bug rather than an isolated setup mistake.
