Live Benchmarking Platform

You can't optimize
what you can't measure.

Container Crucible runs your real containers on production infrastructure and shows you exactly how much performance you're leaving on the table.

"What if your containers could start 240× faster and use 90% fewer resources?"

That's not a hypothetical. That's what the data shows.

Real-Time Comparison

Side-by-Side. No Vendor Spin.

These are measured results from actual container workloads running on identical hardware. Docker on top. Voltainer below. The gap speaks for itself.

How It Works

Three Steps to the Truth

No setup. No infrastructure. No vendor calls. Just data.

01

Choose Your Image

Select from preset images like nginx, redis, or postgres — or upload your own Dockerfile or pull from your private registry.

02

Run the Benchmark

Container Crucible launches your workload on identical hardware under both Docker and Voltainer runtimes. Multiple iterations ensure statistical validity.

03

Get Your Report

Receive a professional PDF with executive summary, comparison charts, detailed metrics, and optimization recommendations — ready to share with leadership.

CI/CD Integration
# Benchmark your image after every build
$ curl -X POST https://crucible.armoredgate.com/api/v1/benchmark \
  -H "X-API-Key: $CRUCIBLE_API_KEY" \
  -d '{"image": "myapp:$BUILD_TAG", "scenarios": ["cold-start", "batch-10"]}'

✓ Benchmark queued — results in ~90 seconds
✓ Report: https://crucible.armoredgate.com/r/a8f2c...
✓ Voltainer cold start: 4ms (vs Docker: 1,340ms) — 335× faster
The Docker Tax

What You're Paying for Without Knowing It

Docker's hidden costs compound across every node, every container, every second of every day.

💾

Storage Duplication

Docker stores glibc, Python, Node.js hundreds of times across images
→ Voltainer stores each unique file exactly once

Startup Overhead

500–2,000ms per container for layer extraction and CoW initialization
→ Voltainer hard-link assembly completes in 1–5ms
📦

Density Ceiling

Per-container overhead limits most nodes to 300–800 containers
→ Voltainer enables 2,000–10,000 containers per node
🔍

Invisible Waste

You can't optimize what you can't measure
→ Container Crucible makes the invisible visible
