Gemma-4-E4B-it (8.0B parameters), served in Q4_0 format with llama.cpp on Jetson Orin NX, starts answering a single camera that sends one 720p image after 1.86 s, then writes 17.2 tok/s.
With 5 images per camera at 720p, the answer starts after 8.32 s. With one 1080p image, after 4.45 s.
At the default target of an answer starting within 3 s (720p, one image per camera), it keeps up with one camera at a time.
