@jaffathecake @slightlylate @RReverser @ericsimons40 @tverwaes @mraleph @mattpocockuk @Neolectron @JeanLouisGouwy @addyosmani @fractorious Hard to say what it could be without looking at the trace info. Will follow up once I’ve taken a closer look

@slightlylate @RReverser @ericsimons40 @tverwaes @mraleph @jaffathecake @mattpocockuk @Neolectron @JeanLouisGouwy @addyosmani @fractorious Yeah the 20s+ delay definitely points to the code being stuck somewhere in an Atomics.wait call, which also somewhat explains why profiling it makes it faster. I don’t expect that the atomic operations themselves are slow though.

@slightlylate @RReverser @ericsimons40 @tverwaes @mraleph @jaffathecake @mattpocockuk @Neolectron @JeanLouisGouwy @addyosmani @fractorious I expect it’s a combination of both of those things, that hardware concurrency isn’t the right gauge for the number of threads and there’s a scheduling issue hiding under there.

@WesGarland4 @commonjs Always! Most if not all of our work is open source. There are more details here for contributing to Wasm, with the links to the community group as well as the discord/IRC channels - https://t.co/vTfRmbGQLs

[Deepti Gandluri @dptig]

Come work with us if you are interested in specifying, and implementing Wasm/JS features! Bonus points if you’re already in the Wasm CG or have some experience with TC39. If these words don’t mean anything to you, but you’re interested, I can also answer questions. :)

[Thomas Lively @tlively52]

Are you interested in working on WebAssembly tooling including Emscripten, Binaryen, and LLVM? My team is hiring! Bonus points if you can help us integrate Emscripten into modern web dev workflows. DM me or @DerekSchuff if you’re interested!

[Deepti Gandluri @dptig]

@binjimint @figmadesign Very cool, congratulations Ben! 🥳

[Alon Zakai @kripken]

I'm curious to know who is using Asyncify with WebAssembly these days? (in any way - with Emscripten, without, etc.)

Details could help with current work on Wasm Stack Switching, which is meant to be a standardized, much more efficient VM-based approach.

@_shu Some of the meal kit services only show you their options if you give them email info. Maybe someone is just using a random email address to bypass giving theirs and that happens to be yours?

[Deepti Gandluri @dptig]

Just recorded this yesterday! Come listen to me talk about all the exciting work happening in the community.

@BillB Is the alternative Covidsgiving?

[Deepti Gandluri @dptig]

@richgel999 @zeuxcg While additional proposals are a hassle to deal with, this doesn't feel like a problem we can solve in one shot given the fragmented hardware landscape. And pushing the MVP out indefinitely is also not ideal as it's frustrating for developers who've now waited for several years.

[Deepti Gandluri @dptig]

@richgel999 @zeuxcg The existing proposal has been in the world for ~3+ years now, and there was an attempt to do this in JS as well which stalled in standardization after a significant amount of work went into it. In the interest of forward progress, we do have to establish an MVP.

[Deepti Gandluri @dptig]

@richgel999 @zeuxcg It's a somewhat hard call to make where to draw the line when balancing different requirements. Where possible we've tried to incorporate feedback to make sure that important operations are included, which is also why we're prototyping the rounding instructions.

[Deepti Gandluri @dptig]

@richgel999 @zeuxcg From a user perspective, having the same applications behave significantly slower on their desktop compared to say a mobile device is also not the best experience. So in some cases we've had to make tradeoffs for consistency.

[Deepti Gandluri @dptig]

Thanks @zeuxcg for your work! From the standards perspective it's been very valuable to engage with and incorporate feedback from real world applications.

[Arseny Kapoulkine 🇺🇦 @zeuxcg]

Oh also v8x16.bitmask et al made it into Wasm SIMD MVP!

I’ve now coauthored two accepted instruction proposals for Wasm SIMD, swizzle (pshufb) and bitmask (movemask), which is two more than I expected; the process has been really straightforward and friendly to outsiders.

[Deepti Gandluri @dptig]

@antonschrein @zeuxcg Still pretty new, but this might be of interest to you - https://t.co/imYn7GxX7w.
