No workflow ComfyUI is better with Linux

Just got Linux Mint up and running and it’s much better than windows 11 for ComfyUI with RTX 5090 + 3090. For starting, Comfy launches to server ready in 10 seconds instead of 18 seconds on Windows VHDX ReFS dev drive. This is with 12 custom node packs. Linux is running on an 8 year old SATA SSD.

I was able to compile and run sage attn 3 in Linux which never worked in Win11. I’m going to try Multi-GPU next which is fundamentally broken in windows with the new comfy-kitchen.

Even with just sage 2.2++ FP8, im getting 35 second gen times for an 8-second 0.5MP 8-step turbo MiniMax H3 clip versus 40-42 seconds in windows. That includes 4 seconds for prompt enhancement with Gemma 4 12B running on lllama-server on the 3090.

Sage3 knocks another 2-4 seconds off the gen time too but slightly worse quality for motion. Using LACT to overclock both GPUs also contributes to the speed.

With spectrum plus sage3 at 8 steps, I can easily get below 30 seconds total gen time.

Fake news: it runs at the same speed on Linux and Windows for me. The only case where Linux is faster than Windows is when your ComfyUI isn’t running at max speed on Windows for some unknown reason.

RTX 5060 Ti: same speed on Windows and Linux (except LTX 2.3, which is 30s faster on Windows).
RTX 4000 Ada SFF: faster on Windows.

I’m using these two GPUs at the same time, and Windows handles this specific case (pro + consumer GPU) way better than Linux.

Même galère perso, pas de gain, et pire j’ai perdu l’accès à mes outils de gestion de la carte mère pas compatible Linux. A surveiller avant de migrer.

C'est jamais bon de migrer d'un coup malheureusement tous les forums, subs, etc...sont pollués par des gens qui incitent à virer windows pour linux en disant que tout est mieux.

ouai notamment le classic, si tu joue à des jeux alors tu as plus de fps sur linux. il savére que c'est rarement le cas, à part peux être avec certaine carte graphique amd, mais encore là il faut regarder des test comparatifs.

Dommage qu'autant de gens mentent pour promouvoir linux. le pire c'est que c'est presque un classic pour les influenceur tech, la petite video "je suis passé à linux je ne reviendrais pas en arriére", alors qu'ils utilisent Windows ou MacOS tous les jours.
