R2 performance issue (ENAM): specific prefix extremely slow via custom domain
Hi Cloudflare team, we’re seeing a reproducible R2 performance issue.
Region: ENAM
Access: R2 behind a custom domain (Cloudflare CDN)
Behavior: Objects under one prefix download at ~32 KB/s, while objects under other prefixes in the same bucket download normally (~800+ KB/s).
Scope: Same client/network and same time; issue is prefix/object-specific (not general).
Request: Please check backend health/routing/object placement for this subset of objects in ENAM.
I can share exact URLs/object keys privately if needed.
