The new system, called Origin Range Requests, is now a self-service feature on all plans, enabled via a Cache Rule with no size to configure. For R2, Cloudflare's object storage, p99 time to first byte dropped by about half on cache hits and misses. A follow-up change that combines cached and freshly fetched bytes in one response cut tiered cache traffic for R2 and similar workloads by about 6% week over week. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What is the Origin Range Requests feature in Cloudflare's cache? It is a self-service Cloudflare feature that serves HTTP range requests using fixed-size cache chunks instead of a manually configured range size. Enabled through a Cache Rule by setting origin_range_requests to 'on', it requires no size tuning and is available on all plans, handling chunking and cache coordination automatically. _Teams configuring CDN caching for large files can track infrastructure changes like this on daily.dev._ ### Why did Cloudflare's old byte-range caching cause wasted bandwidth? The old nginx-based implementation mapped each range request to a fixed configurable size that was also part of the cache key, so a 64 MiB range setting could turn a small read into 128 MiB of cross-datacenter transfer. Small ranges caused many tiny origin requests with memory pressure, while large ranges wasted bandwidth, and concurrent requests in the same range could block each other. _Engineers debugging CDN bandwidth waste can follow architecture postmortems like this via daily.dev._ ### How much did Cloudflare's new range-caching design improve R2 performance? After moving R2, Cloudflare's object storage, to the new Pingora-based chunked caching implementation, p99 time to first byte dropped by roughly half across R2's storage regions on both cache hits and misses. A later change that combines cached and freshly fetched bytes in one response also cut tiered cache traffic for R2 and similar workloads by about 6% week over week. _Developers evaluating object storage performance can keep up with results like this on daily.dev._ ## Community discussion Top comments from developers on daily.dev. **@ristotoldsep** · 0 upvotes > Half the p99 TTFB with less knob-tuning. really nice engineering. ## Similar posts on daily.dev -
