ollama-benchmark is a handy tool to measure the performance and efficiency of LLMs workloads.
Table of Contents
Simple as:
pip install https://github.com/cloudmercato/ollama-benchmark/archive/refs/heads/main.zip
For monitoring you may install Probes:
pip install https://github.com/cloudmercato/Probes/archive/refs/heads/main.zip
ollama-benchmark deliver several workloads:
speed: Evaluate chat speed performanceembedding: Evaluate embedding peformanceload: Evaluate model loading speedjudge: Evaluate answer quality with LLM-as-a-Judgechat: Live evaluate performance while chattinghack: Evaluate against LLM attacks
Please keep in mind the ollama server configuration during evaluation of results. See this part of the FAQ for more understanding of Ollama's performance.
All the common Ollama parameters can be configured through command line options.
This tool allow to run a set of simultaneous requests to the server. The question set is mix of FastChat's MT-Bench dataset and Cloud Mercato's samples allowing computer vision evaluation.
Example:
$ ollama-benchmark speed --question 81 --model llama3 --max-workers 1 --max_turns 1 version: 0.1 model: llama3 question_ids: ["81"] max_workers: 1 max_turns: 1 mirostat: 0 mirostat_eta: 0.1 ... prompt_eval_duration_mean: 161.571 prompt_eval_duration_stdev: 0.0 prompt_eval_rate_mean: 198.05534409021422 <-- Valuable prompt_eval_rate_stdev: 0.0 eval_count_mean: 128 eval_count_stdev: 0.0 prompt_eval_count_mean: 32 prompt_eval_count_stdev: 0.0 eval_duration_mean: 3966.014 eval_duration_stdev: 0.0 eval_rate_mean: 32.27421789232211 eval_rate_stdev: 0.0 total_duration: 4166.39425 <-- Valuable real_duration: 4356.656789779663 <-- Valuable
Evaluate the duration of embedding through different scale of client, different size of input and languages.
Example:

Evaluate the duration of loading one or several models into memory.
Example:
$ ollama-benchmark --host zulumini:11434 load qwen:0.5b qwen:0.5b version: 0.1 models: ["qwen:0.5b"] max_workers: 1 duration_min: 0.5746748447418213 duration_max: 0.5746748447418213 duration_mean: 0.5746748447418213 duration_stdev: 0.0 duration_perc95: 0.5746748447418213 total_duration: 0.5746748447418213 real_duration: 0.6157209873199463 rate_min: 1.7401144475868968 rate_max: 1.7401144475868968 rate_mean: 1.7401144475868968 rate_stdev: 0.0 rate_perc95: 1.7401144475868968 errors: 0
Use LLM-as-a-Judge technic to evaluate quality of given response.
Example:
$ ollama-benchmark judge --question 81 --judge-model llama3 --model qwen:1.8b --max_turns 1 version: 0.1 model: qwen:1.8b judge_model: llama3 question_id: 81 max_turns: 2 mirostat: 0 mirostat_eta: 0.1 ... judge_top_k: 40 judge_top_p: 0.9 judge_min_p: 0.0 message_duration: 1.4621801376342773 judge_duration: 14.956491947174072 work_duration: 16.41867208480835 total_rating_mean: 30 total_rating_stdev: 0.0 total_ratings: [30] 0;evaluation: The answer provides a general overview of the state of Hawaii and mentions two must-see attractions, Waikiki Beach and Haleakala National Park. However, it lacks cultural experiences and details about the trip. 0;feedback: To improve this response, I would suggest providing more specific examples of cultural experiences had during the trip, such as visiting local markets, trying traditional Hawaiian cuisine, or attending a luau. Additionally, including more vivid descriptions of the natural attractions mentioned could make the post more engaging.
Make a live chat in command line and get live performance data.

You can list all hacks with the --show-hacks option.
ollama-benchmark includes a built-in monitoring tool running the time of each workloads. Use following option to control it:
--monitoring-interval: Define the interval between each probe--monitoring-probers: Define probers as Python path (ie: path.to.my.Prober), see Probes' documentation--monitoring-output: Define path to the JSON output--disable-monitoring: Completly disable monitoring
While we try to keep a minimal computational overhead, some probes may incur a duration during starting and stopping.
You can list questions with the following command:
$ ollama-benchmark questions ID | Category | # Turns | Turns 81 | writing | 2 | ['Compose an engaging travel blog post about a recent trip to Hawaii, highlighting cultural experiences and must-see attractions.', 'Rewrite your previous response. Start every sentence with the letter A.'] 82 | writing | 2 | ["Draft a professional email seeking your supervisor's feedback on the 'Quarterly Financial Report' you prepared.
