Minimal baobab Benchmark

A simplified, minimal benchmarking tool for baobab performance testing.

Overview

This benchmark focuses on simplicity and direct timing measurements:

• Creates a single task (n=1) using Lua script
• Measures latency using Redis timestamps
• Uses existing actor binary
• ~85 lines of code total

Usage

Prerequisites

• Redis running on 127.0.0.1:6379
• Actor binary built: cd src/actor && cargo build --release

Run Benchmark

# From project root
cargo bench

Expected Output

🧹 Cleaning up Redis...
🚀 Starting actor...
📝 Creating single task...
⏱️  Waiting for completion...
✅ Task completed in 23.45ms
🧹 Cleaning up...

Files

• simple_bench.rs - Main benchmark binary (85 lines)
• batch_task.lua - Minimal Lua script for task creation (28 lines)
• Cargo.toml - Dependencies and binary configuration
• README.md - This file

How It Works

1. Cleanup: Clear Redis queues and task details
2. Start Actor: Spawn single actor process
3. Create Task: Use Lua script to create one task with timestamp
4. Wait & Measure: Poll task until complete, calculate latency
5. Cleanup: Kill actor and clear Redis

Latency Calculation

latency_ms = updated_at - created_at

Where:

• created_at: Timestamp when task was created (Lua script)
• updated_at: Timestamp when actor completed task

Future Iterations

• Iteration 2: Small batches (n=5, n=10)
• Iteration 3: Larger batches and script complexity
• Iteration 4: Performance optimizations

Benefits

• Easy to Understand: Single file, linear flow
• Direct Timing: Redis timestamps, no complex stats
• Fast to Modify: No abstractions or frameworks
• Reliable: Simple Redis operations
