A merchant tells you: “Our servers are only at 40% CPU, so everything looks healthy.” Five minutes later, customers cannot complete checkout. Both statements can be true. Infrastructure Health Is Only One Layer During peak traffic, teams need visibility across four layers. Infrastructure Monitor: CPU memory disk latency network database connections PHP workers cache hit rate Application Watch: response time PHP exceptions HTTP 5xx responses slow database queries search latency queue depth cron backlog Third Parties Your site may depend on: payment → tax → address

Black Friday isn't the time to discover that checkout fails under load or inventory stops synchronizing. Peak-season preparation should begin before the traffic arrives. Performance & Infrastructure Establish a Baseline Measure normal response times, errors and infrastructure utilization. Review Capacity Evaluate expected traffic against application, database, cache and search capacity. Load-Test Real Journeys Don't test only the homepage. Test: Browse → Search → Product → Cart → Checkout → Order Commerce

Adobe Commerce and Magento can support highly sophisticated commerce experiences. That flexibility also creates complexity. When performance deteriorates, there is rarely one universal fix. Here are ten areas worth investigating. 1. Infrastructure Doesn't Match the Workload Traffic, catalog size, indexing, customer groups and integrations all affect resource requirements. Measure CPU, memory, database activity, disk I/O and network behavior under realistic workloads. 2. Caching Isn't Working Effectively If pages
