Dramatic Performance Gains

157x throughput increase and 117x faster response times with Varnish HTTP caching.

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.
