Will Lazy Summaries affect my Squarespace site speed?
Lazy Summaries can add load on large collections. The "Load all" option requests all items at once, which is slow for big collections; the Load More button and session-storage cache mitigate this by lazy-loading items in batches and caching repeat loads. Use Load More rather than Load all for performance on large collections.
Performance considerations
The “Load all” option requests all items at once, which is slow for large collections because the browser fetches and renders everything up front. The Load More button reveals items in batches instead, reducing the initial payload (Squarewebsites).
Caching
Lazy Summaries uses session-storage caching to speed up repeat loads within the same browser session. This helps return visitors but does not speed up the first load of a large collection (Squarewebsites).
Recommendation
For collections with many items, prefer Load More over Load all to keep the page responsive, and let the session cache handle subsequent views.
