How We Cut Vision Transformer Inference Latency from 53 ms to 8 ms

Facing 53.64 ms per‑image latency in a Flask‑served Vision Transformer classifier, we iteratively optimized the pipeline—switching to ONNX Runtime, leveraging TensorRT, replacing Pillow with OpenCV, eliminating URL downloads, and finally batching requests—reducing average server‑side processing to 8.34 ms, a 6.4× speedup.
