Aero Commerce Varnish Integration

Experimental Varnish cache integration for Aero Commerce demonstrating order-of-magnitude performance improvements through HTTP caching. Load testing showed 157x throughput increase and 117x faster response times.

Problem

Aero Commerce, an emerging ecommerce platform, needed to handle high traffic loads efficiently. Without HTTP caching, backend PHP execution limited throughput to 21 requests/second with 6-second p95 response times.

Solution

Impact

The following performance comparison was performed on a Hetzner CPX31 server (4vcpu, 8GB memory)

Technical Highlights

backend default {
    .host = "127.0.0.1";
    .port = "8080";
}

sub vcl_recv {
    if (req.url ~ "/cart|/checkout") {
        return (pass);
    }
}

• Cache hit rate optimization (~90%+)
• Dynamic content bypass for cart/checkout
• Integration with Aero’s architecture
• Potential for ESI implementation for personalized content
