Now, we’ve optimized how ISR cache updates work, leading to: Faster revalidations with lower Time to First Byte (TTFB) More efficient cache updates, reducing compute overhead Greater cost efficiency, with up to 65% savings on ISR reads and writes These improvements require no configuration changes—just redeploy to get the benefits. Link to heading What’s new: Faster, more efficient ISR Vercel has been continuously improving our support for ISR since it was first introduced. Our latest updates focus on speed and cost efficiency, with two major improvements: Link to heading Faster: Regionalized caching ISR cache entries are now stored in the same region as your functions, meaning: Lower latency for cache retrieval Faster revalidations when regenerating content Better performance for global users, especially those outside North America Regionalized ISR improves TTFB latency by up to 80% when an ISR cache read occurs within the same geographic area.…
