Thu Sep 26 13:00:00 UTC 2024: ## Cloudflare Boosts Workers KV Performance, Delivering Up to 3x Faster Read Speeds

**San Francisco, CA – October 2023** – Cloudflare, the global network for the Internet, today announced significant performance enhancements to its Workers KV service, resulting in up to 3x faster hot read speeds and overall latency reductions of up to 20 milliseconds for all KV operations.

“Speed is critical for a great Internet experience,” said [Cloudflare spokesperson], “Every millisecond a user waits for a webpage to load increases the likelihood of them abandoning your website. We believe a faster Internet is a better Internet, and these improvements to Workers KV directly impact the performance of countless websites and services built on Cloudflare.”

Workers KV is a key-value data storage service that enables developers to store and retrieve data for configuration, routing, personalization, and more. Many of Cloudflare’s own products rely on KV, including Pages, Access, AI Gateway, and Images.

Cloudflare engineers achieved these significant performance gains through several key optimizations:

* **Direct Binding to Cache:** Workers KV bindings now connect directly to the KV Worker within the same Cloudflare location, eliminating the need for intermediate layers and reducing latency by 10 milliseconds.
* **Tiered Cache:** A new cache topology with regional tiers in addition to local tiers ensures more requests are resolved closer to the user, reducing the need to access centralized storage backends and significantly improving read latency.
* **In-Memory Cache for Hot Keys:** The hottest keys (those accessed most frequently) are now cached within the KV Worker’s memory, eliminating the need for network hops and resulting in read times of under a millisecond for over 40% of global Workers KV requests.

These optimizations have already delivered measurable improvements across Cloudflare services and customer websites:

* **Cloudflare Pages:** Saw load times for fetching assets improve by up to 68%.
* **Workers Asset Hosting:** Benefits from these performance gains from day one.
* **Queues and Access:** Experienced 2-5x faster read operations, leading to overall faster performance for these services.

“These improvements to Workers KV demonstrate our ongoing commitment to pushing the boundaries of performance and delivering a faster, more reliable Internet for everyone,” said [Cloudflare spokesperson].

Customers using Workers KV can view detailed latency and cache status per namespace in their Cloudflare dashboard to see the recent speed gains firsthand.
