Crate elara_loadtest 

Load testing framework for the ELARA Protocol

This crate provides comprehensive load testing capabilities for validating ELARA Protocol performance under realistic deployment scenarios with multiple nodes.

Features

• Simulate multiple nodes in a single process
• Generate realistic message patterns with ramp-up and sustained load
• Measure end-to-end latency with accurate timestamps
• Track message success/failure rates
• Calculate latency percentiles (p50, p95, p99)
• Generate comprehensive reports with statistical analysis
• Predefined scenarios for small (10), medium (100), and large (1000) node deployments

Example

use elara_loadtest::{LoadTestScenario, scenarios};

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    // Use predefined medium deployment scenario
    let config = scenarios::medium_deployment();
    let mut scenario = LoadTestScenario::new(config);
     
    // Run the load test
    let result = scenario.run().await?;
     
    // Print results
    println!("Throughput: {:.2} msg/sec", result.throughput_msg_per_sec);
    println!("P95 Latency: {:.2}ms", result.p95_latency_ms);
     
    Ok(())
}
