I open settings in an app by a company valued at >$15B. the ui is different. I get a popup: "settings is under construction". audibly sighed out loud.

I used LLRT's Lambda release without the SDK. I tried round-trip latency but couldn't get good measurements, but I'm not an AWS person. I think duration is most important as this is specifically cold starts but happy to follow up.

Thanks! Yes, there are a surprisingly number of use cases and embedded is a big one like any environment where you can't JIT but want better performance then interpreting.
For embedded you can either use Wasm or Porffor's compile to C feature and give that to some proprietary compiler, etc

Yeah afaik that is just AWS overhead

My ahead-of-time JS engine Porffor eliminates JS cold starts on AWS Lambda. 12x faster and 2x cheaper than managed Node. Still very early but these results should speak for themselves :)

potential outcomes:
- we both waste 5 minutes
- I waste a few hours
- we cry with joy :)

If you have AWS Lambdas with a small amount of (Node)JS please DM me :)

Oh yeah, but I mean it relies on the engine itself having asan etc

Yeah, Fuzzili is very cool but hard to integrate, especially since it is made for being used with coverage and sanitizers which I don't have 😅

I like the idea of using a small model but I think it would heavily limit throughput. It currently runs >1k cases/second and it would probably be much less even with a tiny model running locally 😅

Porffor now passes over 60% of Test262, thanks to a new custom regex engine!

Porffor now has its own fuzzer which abuses the compiler with randomly generated JS code in an attempt to find bugs which would otherwise not be found to help stability!

Porffor's Wasm is now faster than *native* Node JITless at richards.js, an old V8 benchmark!
new improvement is thanks to a new compiler feature and a minor object rewrite I'll post about this weekend. I still have ideas which can make this hopefully almost 2x faster this month!
