I agree that Electron is a bottleneck. That's something they'll have to deal with. However, there's a small difference between what this post is saying and what you're saying: "24x - 1400x fafster depending on what you're measuring" is quite different to "[the changes are] not really helpful". Regardless, I'm glad to see that they're embracing Rust in some way, distancing themselves from javascript. I hope the SDK will be good enough for a bustling ecosystem of efficient clients (and servers!). I'm also glad that people like you and I are making it clear that we value the reduction of sludge, we value efficiency and therefore inclusion for everyone, including those who have devices that aren't that powerful.
