ComfyUI reloads models from disk on every run; --disable-dynamic-vram is the workaround
Silver-Spot-2763 · reddit · 2026-09-06
A Reddit user details a long-standing ComfyUI pain point: by default it reloads the full encoder, model and VAEs from disk on every RUN — very slow on slow drives and wasteful. The only fix is the --disable-dynamic-vram flag, at the cost of 15% more RAM: the H3 convrot int8 pruned model goes from 35GB to 48GB (peaking at 61GB) on a Windows 11 machine with 64GB RAM and RTX 3060 12GB, flirting with page-file swapping. The author fears the flag may be removed entirely and urges the team to fix the reloading behavior.
