Link Preloading — Instant Page Navigation

Preloading watches the page you are on, identifies links you are likely to click, and begins loading those destination pages in the background before you act. When you do click, the page is already partially or fully loaded — navigation feels near-instant. Both levels of preloading are free.

How It Works

SuperchargePerformance identifies links on the current page that you are likely to click next, then begins loading those destination pages in the background. When you navigate to a preloaded URL, the content is already cached — so the page appears near-instantly rather than starting a cold network request.

Preloading is a bandwidth trade-off: you use some data fetching pages you may not visit in exchange for dramatically faster navigation when you do visit them. On fast, unlimited connections this trade-off is almost always worth it.

Settings

The default is Level 2 (All pages). This provides the broadest navigation speedup across the web. Switch to Level 1 if you prefer to avoid cross-site prefetch requests, or disable Preloading entirely if you are on a metered connection.

When to Use This

• You browse multi-page content (articles, documentation, product listings) and click through pages sequentially
• Navigation between pages feels sluggish even though your connection is fast
• You want the most noticeable speed improvement without changing how pages look
• You are on an unlimited broadband connection where the extra bandwidth cost is negligible

Preloading pairs well with Resource Prioritization: Resource Prioritization makes the current page load faster, while Preloading makes the next page load faster.

Privacy

Preloading makes network requests to pages linked from your current page — this is inherent to how prefetching works. Level 1 limits these requests to the same domain, eliminating cross-site network exposure. Level 2 includes safeguards to avoid patterns that could be used for tracking. No browsing history, click patterns, or page content is sent to SuperchargePerformance or any third party.
