Optimizing AEM 6.5 On-Premise for High Performance -Part 1

Adobe Experience Manager (AEM) 6.5 on-premise is a powerful content management system, but optimizing its performance is crucial for handling high-traffic websites efficiently. This article covers key performance optimizations implemented on the AEM Dispatcher and Publisher (Part 2) to enhance scalability and response times.

Dispatcher Optimization

Apache Multi-Processing Modules (MPMs)

Apache MPMs control how requests are processed. The event MPM was used for better handling of long-lived or idle connections. Key configurations:

• StartServers: Adjusted based on traffic, typically set between 2–5.
• MinSpareThreads & MaxSpareThreads: Optimized for peak traffic to ensure availability.
• ThreadLimit & ThreadsPerChild: Configured to balance memory use and concurrency.
• MaxRequestWorkers: Increased to prevent request rejections.
• MaxConnectionsPerChild: Set between 1000–5000 to prevent memory leaks.
• AsyncRequestWorkerFactor: Tuned to optimize latency.
• ServerLimit: Adjusted to match server capacity.
