VSCode's problem isn't that it's slow, it's that it's bloated. It takes a bit over 1GB memory (in my testing) to open the same files that Sublime can do in just 200-300 MB. In my book, it is simply not acceptable to waste my memory like that.
I just tried opening a 730 MB file in both and VSCode's usage was just around 2 GB while Sublime's usage (fresh install) was over 3 GB. This is even with my normal VSCode extensions enabled (91 currently).
