It’s also important to remember that writing native apps doesn’t inherently inherently give you a big performance boost. With the type of app Slack has, I would expect the default implementation in a native app to be pretty slow as well. You’d have to do a significant amount of further optimization to make it competitive, imo. And to be honest, I imagine if someone applied that same amount of optimization and effort to the electron app, they could make the performance much better there as well.
