In serverless computing, speed is paramount, not just for optimizing development time, but crucially for the relationship between performance and operational costs. In our hyperconnected world, where rapid information access is essential, those who can leverage this concept at scale will benefit from reduced cloud costs. Rust is emerging as a key language for unlocking the performance of next-generation serverless applications. Recently, JavaScript engines like Deno and Bun have sought to improve performance using low-level languages such as Rust and Zig. However, these often include APIs and code superfluous in serverless environments. We introduce LLRT, a low-latency runtime specifically designed to maximize AWS Lambda performance for JavaScript developers. Optimized for serverless environments, LLRT eliminates unnecessary components, offering ultra-fast information access and significant cloud cost reductions.
