New Relic migrated its Lambda Extension from Go to Rust, resulting in a 40% reduction in billed duration and improved memory efficiency. The rewrite also enhanced reliability and introduced a more robust telemetry pipeline.

AWS Lambda response streaming has increased its maximum response payload size to 200 MB, ten times the previous limit, enhancing performance for latency-sensitive applications. This improvement allows for direct processing of large datasets and media files without the need for intermediate services, thereby reducing time to first byte (TTFB) for end-users. The new limit is applicable across all supported AWS Regions and compatible with both Node.js managed and custom runtimes.
