Performance Issues and Mitigation Strategies for Salesforce Lightning Experience
This article outlines common geographic, device, browser, and Salesforce org configuration problems that cause slow page loads in Lightning Experience and provides practical mitigation steps such as network latency testing, browser benchmarking, disabling unnecessary plugins, and optimizing Visualforce and Lightning page designs.
Geographic Issues
Accessing the host from distant locations can cause latency due to network distance or VPN routing before reaching the Salesforce org.
Potential mitigation: Evaluate network latency using ping or traceroute, measure download/upload speeds, and consider optimizing the network path.
Device and Browser‑Related Issues
Insufficient CPU or memory on laptops, desktops, or VDI, as well as resource‑heavy browser plugins, extensions, or many open tabs, can degrade Lightning performance.
Potential mitigation:
Assess browser processing capability: Use Octane ( https://chromium.github.io/octane/ ) to benchmark; values below 15000 may indicate slow performance. Improve the score by charging laptops, closing other apps, resetting browser settings, removing unnecessary extensions, or upgrading hardware.
Disable unnecessary plugins and extensions (e.g., via chrome://plugins/ or chrome://extensions/ ).
Use the latest browser version or apply patches.
Switch to a faster browser such as Chrome.
Restart the browser and device regularly to free resources.
Salesforce Org Configuration
Unoptimized Visualforce implementations.
Enabled Aura debug mode.
Complex Lightning pages with many components or fields.
Potential mitigation:
Optimize Visualforce pages: Follow best‑practice guidelines in the Visualforce performance developer guide.
Disable Aura debug mode: Turn off the “Enable Debug Mode” checkbox in Setup → Lightning Components.
Reconfigure processing‑intensive pages: Reduce the number of visible fields, use tabs to defer rendering of secondary components, streamline related lists, and test custom components for impact.
Lightning Component Best Practices
Refer to the Lightning Experience performance best‑practice documentation for additional guidance.
