Stalwart v1.0, after five years of development, is announced as the fastest mail server on the planet, outperforming widely used Postfix 3.11 and Dovecot 2.4 stacks in 35 of 38 performance benchmarks. This release focused on optimizing every server component for speed and stabilizing the database schema to allow seamless future upgrades without disruptive migrations. New full-text search capabilities inside PDFs and office documents were added. Stalwart's performance improvements involved extensive profiling and rewriting of parsing libraries, caching strategies, and database interactions, measured rigorously on Azure labs. Key speed achievements include executing full-text search on 250,000 messages in under 4 milliseconds and moving or deleting large message sets over 200 times faster than Dovecot. Migration tools and guides support upgrading from previous versions or switching from other mail servers, with focus on data integrity and minimal downtime. The project credits community contributions for its progress and invites feedback on the stable release.
