WinterJS vs. Bun: Comparing JavaScript runtimes
Below, we can see Bun’s performance: In this specific example, you can see that Bun performs better than WinterJS on my computer. WinterJS is said to run much better natively than when it runs using Wasmer, so this explains its underperformance in this test. A native result might look something like this instead: The sample result above comes from the WinterJS GitHub and shows how it does better natively with this very simple test.

The Upper Limits of WebAssembly Performance
Wasmer.io recently released an article announcing their Winter.js 1.0, however looking at the details of their benchmarks it shows that running Winter.js in wasm results in a 12x slow down in performance compared to native.

Is AWS Lambda Cold Start Still an Issue?
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.

JavaScript News, Updates, and Tutorials: February 2024 Edition
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.

People Matter more than Technology when Building Serverless Applications
And lastly, lean into your cloud vendor. Stop trying to build a better mouse trap. Advances in technology are happening all the time. The speed of AWS' Lambda has been rapidly improving over the past couple of years with the launch of things like SnapStart and LLRT

LLRT: A low-latency JavaScript runtime from AWS
It seems they just added the mention to QuickJS, I assume, based on your feedback:
https://github.com/awslabs/llrt/commit/054aefc4d8486f738ed3a...
Props to them on the quick fix!
