CPU Usage Testing

This directory contains test scripts and configurations for measuring Replicate's idle CPU usage, particularly for validating the fixes in issue #992.

Files

test-cpu-usage.sh - Automated CPU monitoring script
replicate-test-polling.yml - Config for testing with S3 replication

Prerequisites

Build Replicate binary:

cd ../..
go build -o bin/replicate ./cmd/replicate

Set up AWS credentials in .envrc at repo root:

export AWS_ACCESS_KEY_ID="your-key-id"
export AWS_SECRET_ACCESS_KEY="your-secret-key"
export AWS_REGION="us-east-2"
export S3_BUCKET="your-test-bucket"

Have sqlite3 CLI installed

Usage

From this directory, run:

# Test for 60 seconds
./test-cpu-usage.sh 60

# Longer test (5 minutes)
./test-cpu-usage.sh 300

What It Tests

The script:

Creates a test SQLite database at /tmp/test.db
Starts Replicate with S3 replication
Monitors CPU usage every second using ps
Calculates average CPU usage
Verifies S3 replication is working
Outputs results and detailed CSV log

Expected Results

Based on testing for PR #993:

With S3 transport fix: ~0.0067% CPU (99% improvement)
Original (v0.5.6): ~0.7% CPU

The S3 transport fix achieves near-zero idle CPU usage, validating the fix.

Output

Results are printed to stdout and detailed logs are saved to:

/tmp/replicate-cpu-log.csv - Per-second CPU measurements

Notes

Tests require real S3 credentials and will upload data to your bucket
Test database is created at /tmp/test.db and cleaned up on each run
CPU measurements are instantaneous snapshots, not averages over intervals
Longer test durations (5-10 minutes) provide more stable averages
