Oh, the original comment was about the WebKit wrapper. Well, that this is using as much memory isn't very surprising. Why would Slack use less memory in a WKWebView than in an Electron frame? It is essentially the same app (with the Electron app providing a set of extra platform integration benefits). Any performance differences between the two approaches should essentially boil down to the Chrome vs Safari differences.
