Latency tests

• Input length: 32 tokens.
• Output length: 128 tokens.
• Batch size: fixed (8).
• Models: llama-3.1 8B, llama-3 70B, mixtral 8x7B.
• Evaluation metrics: end-to-end latency (mean, median, p99).

Throughput tests

• Input length: randomly sample 200 prompts from ShareGPT dataset (with fixed random seed).
• Output length: the corresponding output length of these 200 prompts.
• Batch size: dynamically determined by vllm to achieve maximum throughput.
• Models: llama-3.1 8B, llama-3 70B, mixtral 8x7B.
• Evaluation metrics: throughput.

Serving tests

• Input length: randomly sample 200 prompts from ShareGPT dataset (with fixed random seed).
• Output length: the corresponding output length of these 200 prompts.
• Batch size: dynamically determined by vllm and the arrival pattern of the requests.
• Average QPS (query per second): 1, 4, 16 and inf. QPS = inf means all requests come at once. For other QPS values, the arrival time of each query is determined using a random Poisson process (with fixed random seed).
• Models: llama-3.1 8B, llama-3 70B, mixtral 8x7B.
• We also added a speculative decoding test for llama-3 70B, under QPS 2
• Evaluation metrics: throughput, TTFT (time to the first token, with mean, median and p99), ITL (inter-token latency, with mean, median and p99).

json version of the benchmarking tables

This section contains the data of the markdown tables above in JSON format. You can load the benchmarking tables into pandas dataframes as follows:

import json
import pandas as pd

benchmarking_results_json = """The json string"""
benchmarking_results = json.loads(benchmarking_results_json)
latency_results = pd.DataFrame.from_dict(benchmarking_results["latency"])
throughput_results = pd.DataFrame.from_dict(benchmarking_results["throughput"])
serving_results = pd.DataFrame.from_dict(benchmarking_results["serving"])

The json string for all benchmarking tables:
