Cloudflare Cuts 100 TB of Memory from 1.1.1.1 DNS Cache

Cloudflare has redesigned the in-memory representation of the DNS cache used by its 1.1.1.1 resolver, reducing the benchmarked per-entry footprint by 56% and freeing roughly 100 TB of working-set memory across its fleet. The changes to Big Pineapple, Cloudflare's DNS platform, also increased cache insertion throughput by 43% and reduced lookup latency by 19%.
