## AI overview

Neon describes storage performance improvements focused on ingest latency, read amplification, bandwidth usage, and the write-ahead-log path to S3. WAL is decoded centrally at Safekeepers and routed only to the relevant Pageserver shard, reducing redundant processing and network traffic. The changes produced about 2x higher ingest throughput for large sharded tenants, an 87.5% reduction in Pageserver WAL decoding work with eight shards, and roughly 50% lower cumulative time for a 200 GB COPY import in staging.

## Source excerpt

Neon's storage architecture is designed for scalability, but scalability alone doesn't guarantee performance. Over the past several months, we've been focused on making the Neon storage system faster - cutting down ingest latency, reducing read amplification, making better use of...
