A predictable application surge requires deliberate performance engineering, traffic management, and scale testing.

First, expensive synchronous processing should be reduced or moved to asynchronous execution where practical. Salesforce Experience Cloud supports high-volume record creation patterns that collect requests and process them asynchronously in batches, helping the site continue handling traffic during spikes. Second, a Content Delivery Network (CDN) reduces load on the Salesforce origin by distributing and caching eligible content closer to users. Salesforce recommends CDN-based delivery for high-traffic Experience Cloud sites because it improves page-load performance and reduces processing pressure during periods of heavy concurrent access. Traffic-control or waiting-room patterns can additionally regulate extreme arrival bursts before they reach the application tier. Third, the application must undergo realistic performance and scale testing based on expected concurrency, traffic, transactions, and customizations. UAT validates functional correctness but does not establish production-scale capacity. IP restrictions would arbitrarily reduce access rather than engineer the system to withstand legitimate constituent demand.
