What’s the point of an outstanding website design and well-crafted user experience if your back end can’t handle all those intricate features?
AEM allows you to create great front-end implementations and design. Check ✔. However, a strong back end has to support them, for every additional second of delay on the back end can result in a blank screen, functional errors, slow page speed — and, worse yet — visitors leaving your site.
Adobe Experience Manager back-end performance requires fine-tuning.
Our previous article highlighted the top 9 website page speed issues on the front end. Now, our AEM implementation experts would like to examine Adobe Experience Manager back-end performance issues—and ways to fix them.
Address AEM Back-End Performance Issues And Get your Servers Running Like Clockwork
Action 1. Configure the Server
Adobe Experience Manager is a complicated system of interconnected components. Some components will inevitably work well, while others will lag behind. Each component requires processing power drawn from the server’s capacity.
On the server side, high central processing unit (CPU) consumption and memory issues can negatively impact AEM back-end performance.
Solution:
To detect and prevent AEM back-end performance hiccups, monitor CPU and memory spikes to determine what needs tuning and which heavy-running processes need optimization.
Ensure CPU and memory resources are properly allocated for your project and content needs. After analyzing your CPU and memory consumption data, you can decide whether to scale up the server capacity or optimize the existing code.
Fine-Tune Background Processes
95% of the time, your server does something users are unaware of. Responses to web requests are prepared, new content is published, obsolete data is backed up or retired, binary storage is compactified or maintained, and external data is imported.
These actions often happen simultaneously. They consume much of the server’s resources, which ultimately causes AEM back-end performance issues.
Solution:
Pick the correct number of server instances, provide load balancing between them, and schedule the most demanding processes for the least busy times. Set up logging and alerts to let developers and support teams know what’s in progress and what’s going wrong.
Action 2. Use AEM Best Programming Practices
Lack of coding experience can provoke AEM back-end issues and make rookie programmers stumble now and then.
Solution:
Know possible workarounds to prevent AEM back-end performance bottlenecks:
- Use separate non-AEM-based services for massive data writes or updates, such as user profiles, user reactions, or bookmarking.
- Avoid putting too many separate components on a single page. Doing so will lead to poor web performance in authoring mode.
- Don’t stuff the entire initialization logic into the back-end page rendering process while slowing down loading. Let your markup be lightweight and basic so that each subsequent request from the same user loads new data or content when scrolling further down.
- Close connections and sessions that aren’t running anymore and set limits to their runtime.
- Instead of @Inject, use specific injector annotations such as @ValueMapValue when applying Sling models.
