Hello,
i have build a homelab from used components:
z840 hp workstation
Intel® Xeon® CPU E5-2683 v4 @ 2.10GHz 2.10 GHz (2 processors)
128 GB RAM
Nvidia Quadro K2200 - 4GB
Tesla p40 24GB
i use Automatic1111 and ComfyUI and i’m not sure if my performance is the best or something is missing, so here is my results on AUtomatic1111 with these Commanline: -opt-sdp-attention --upcast-sampling --api
Prompt

for ComfyUI, it took ages on the first generation, i think because it try to load the model and these are the results on the same prompts with the default workfolow:

please note the difference between first prompt it/s and the secont prompt sec/it on Automatic1111.
is this the best performance i can get, or is there is some tweaks that can make performance better ?
I’ve been thinking of getting one of these because a 3090 is too much $$$. It varies depending on exactly what the task is, but it’s about half a 3090.
There are threads here on this. Here is one that I bookmarked when I was considering buying a p40. https://www.reddit.com/r/LocalLLaMA/s/sjJ84nsppG
You might want to ask over there.
