ComfyUI-Tenaciousload

# ComfyUI-Tenaciousload Self-contained fix for slow / black-screen ComfyUI loading when you have a huge model/LoRA collection (especially on a network mount). **Just install the pack and restart ComfyUI — no nginx, no docker, no extra port.** ## The problem ComfyUI's `/api/object_info` enumerates every node's inputs. With thousands of LoRAs (worse on a network mount) it becomes tens of MB and takes **minutes to build on every page load** — and the build **freezes ComfyUI's whole event loop**, so you get a long black screen, worst over a remote network. ## How this pack fixes it

How it works: requests are served from an in-process cache in milliseconds; the slow build only runs on a miss or refresh

On load it injects an aiohttp **middleware** into ComfyUI that intercepts `/object_info` and `/api/object_info` and: - **caches the built response in memory _and_ on disk** (`./cache/`), so it is built once instead of on every load — and the disk copy makes **restarts instant** (no rebuild); - **serves it gzipped in ~milliseconds** (≈85% smaller, independent of any CLI flag); - serves from cache **without running the build**, so the event-loop freeze is gone for normal loads. The only time a build runs is the first load after install, or when you explicitly refresh (below). ## Refreshing after you add / remove models or LoRAs The cache holds the old model lists until you refresh, so new files won't appear until you do one of: - **Menu:** `Extensions ▸ 🔄 Refresh Models / LoRAs` (also in the command palette). - **Graph node:** `🔄 Refresh Models/LoRAs (Tenaciousload)` (for automated workflows). - **HTTP:** `POST /tenaciousload/refresh`, then `GET /object_info?nocache=1`. A refresh re-walks your model folders (slow over a network mount, ~minutes) — the button shows a "refreshing…" toast meanwhile. Normal loads stay instant. ## Requirements **None to install.** Only ComfyUI itself (tested on 0.23.0) and Python ≥ 3.8. Everything used is Python stdlib or already bundled with ComfyUI (`aiohttp`, `folder_paths`, `server`). The web button needs no npm packages. ## Install Clone (or copy) this repo into your ComfyUI `custom_nodes/` folder and restart ComfyUI: ```bash cd ComfyUI/custom_nodes git clone https://github.com/ethanfel/ComfyUI-Tenaciousload.git # then restart ComfyUI ``` Nothing to `pip install`. ComfyUI-Manager can also install it from the registry. ## Verify it's working After restart, load the page once (first time builds + caches), then: ```bash curl -s -H 'Accept-Encoding: gzip' -o /dev/null \ -w '%{time_total}s | %{size_download} bytes | %header{x-tenaciousload-cache} | %header{content-encoding}\n' \ http://127.0.0.1:8188/api/object_info # use your ComfyUI port # expect after the first load: ~0.00Xs | ~10 MB | HIT | gzip ``` ComfyUI's startup log should show `Tenaciousload: object_info cache middleware installed`. ## Notes - The disk cache lives in `./cache/` (git-ignored). Delete it, or use the refresh button, to force a rebuild. - An nginx reverse proxy can cache `object_info` at the HTTP layer too, but this pack does it in-process so no extra service, container, or port is needed. ## License MIT — see [LICENSE](LICENSE).
