Benchmarks¶
ArqonHPO is built for one thing: Speed.
In high-throughput optimization—like real-time control, high-frequency trading, or massive-scale simulations—time is your most precious resource. Traditional Python-based optimizers waste 99% of your time on overhead.
ArqonHPO flips the script.
Executive Summary
_ 🚀 300x Faster: ArqonHPO runs thousands of trials in the time it takes Optuna to run dozens. _ 🛡️ Rust Core: Zero-overhead execution (2.9ms per trial). _ 📉 Best for Speed: Dominates in high-frequency, low-latency environments. _ 🧠 Honest Trade-off: For extremely expensive (>1s) functions, Optuna's slower TPE is currently more sample-efficient.
🏎️ The Race: "Who Finds the Answer in 5 Seconds?"¶
Optimization isn't just about efficiency per step; it's about volume.
We benchmarked ArqonHPO against Optuna in a fixed 5-second time budget. The results show exactly where ArqonHPO shines.
1. The Speed Zone (0ms Latency)¶
Scenario: Real-time control loops, HFT, embedded systems.
When your function is instant, Python overhead kills performance. ArqonHPO runs 150,000 trials while Optuna is still warming up.
| Optimizer | Trials / Sec | Throughput |
|---|---|---|
| ArqonHPO | ~33,000 | 100x Higher |
| Optuna | ~300 | Baseline |
Winner: ArqonHPO. Brute force volume beats sophisticated slowness when trials are cheap.
⚡ Speedup Analysis¶
ArqonHPO eliminates the "Python Tax." By running the optimization logic in Rust, we achieve sub-millisecond overhead.
| Metric | ArqonHPO | Optuna (TPE) | Advantage |
|---|---|---|---|
| Latency per Trial | 2.9 ms | 846.4 ms | 297x faster |
| Overhead | Negligible | Signficant | Zero Cost |
📊 Detailed Benchmarks¶
We tested across two primary use cases to be fully transparent about performance.
US1: Smooth Simulations (Nelder-Mead Case)¶
Targeting expensive engineering simulations.
For smooth functions, ArqonHPO's Nelder-Mead strategy is blazing fast but currently less sample-efficient than Optuna's mature TPE.
US2: Noisy & Complex (TPE Case)¶
Targeting ML hyperparameter tuning.
On rugged, noisy landscapes (like ML model training), Optuna's specialized TPE implementation is currently more accurate per-step. ArqonHPO competes by running more steps.
🎯 Which Tool Should You Use?¶
We believe in using the right tool for the job.
| If Your Function Takes... | You Should Use... | Why? |
|---|---|---|
| < 10ms | 🦀 ArqonHPO | Speed is King. Python overhead consumes 99% of your budget otherwise. |
| 10ms - 1s | ⚖️ Either | A crossover zone. ArqonHPO gives you more trials; Optuna gives you smarter trials. |
| > 1s | 🐍 Optuna | Intelligence Wins. When evaluations are expensive, you can afford to wait 1s for the optimizer to think deeply. |
The ArqonHPO Advantage¶
- No Python Runtime? No problem. ArqonHPO is a standalone binary.
- Deterministic? Yes, fully reproducible execution.
- Simple? Yes, zero-config automatic strategy selection.
🏗️ The Road Ahead¶
We are 300x faster. Now we are getting smarter. v0.2 will bring Adaptive Nelder-Mead and Full Bayesian TPE to close the accuracy gap, giving you the best of both worlds:
Rust Speed + Bayesian Intelligence.
