The table below shows latency measurement, which typically involves assessing the time from when the system receives an input to when the model produces a result.
For FP16 models, remove `--quantization fp8 --kv-cache-dtype fp8`.

When measuring models with long context lengths, performance may improve by setting `--max-model-len` to a smaller value. It is important, however, to ensure that the `--max-model-len` is at least as large as the IN + OUT token counts.

`rocm/vllm-dev:main` image has experimental [AITER](https://github.com/ROCm/aiter) support, and can yield siginficant performance increase for some model/input/output/batch size configurations. To enable the feature make sure the following environment is set: `VLLM_USE_AITER=1`, the default value is `0`. When building your own image follow the [Docker build steps](#Docker-manifest) using the [aiter_integration_final](https://github.com/ROCm/vllm/tree/aiter_integration_final) branch.
