Workers KV has completed rolling out performance improvements across all KV namespaces, providing a significant latency reduction on read operations for all KV users. This is due to architectural changes to KV's underlying storage infrastructure, which introduces a new metadata later and substantially improves redundancy.

#### Performance improvements

The new hybrid architecture delivers substantial latency reductions throughout Europe, Asia, Middle East, Africa regions. Over the past 2 weeks, we have observed the following:

- **p95 latency**: Reduced from \~150ms to \~50ms (67% decrease)
- **p99 latency**: Reduced from \~350ms to \~250ms (29% decrease)
