When I think about a fast editor I think about opening a 2GB log file and looking for some text, or editing a multi-megabyte Markdown file with syntax highlighting on without any slowdown (something my NeoVim currently struggles with).
I just opened a 4GB JSON file in VScode, it took a few seconds to load, but it is fast enough for me. Syntax highlighting disabled itself, but searching text works.
