  • LLRT: A low-latency JavaScript runtime from AWS
    10 projects | news.ycombinator.com | 8 Feb 2024
    LLRT is built using Rust, Tokio and QuickJS under the hood.

    We (at Wasmer), have been working on a very similar approach: WinterJS, which is using SpiderMonkey instead (but also built on top of Rust and Tokio). https://github.com/wasmer/winterjs

    It would also be nice to have a V8/deno/bun based edge hosting option that supports the Next.js edge and middleware code splitting. That's the missing piece for most homebrew "edge" setups. Production CDNs like Clouflare and Supabase all offer this.

  • Is AWS Lambda Cold Start Still an Issue?
    2 projects | dev.to | 18 Mar 2024
    Let’s get the simplest use case out of the way: cases where the cold starts are so fast that it’s not an issue for you. That’s usually the case for function that use runtimes such as C++, Go, Rust, and LLRT. However, you must follow the best practices and optimizations in every runtime to maintain a low impact cold start.

    But compared to other runtimes, LLRT is not so good in terms of performance when it comes to dealing with large data processing, Monte Carlo simulations, or performing tasks with a large number of iterations. The AWS team says that it is best suited for working with smaller Serverless functions dedicated to tasks such as data transformation, real-time processing, AWS service integrations, authorization, validation, etc. Visit the GitHub repository of this project to learn more information.
