fwiw, I have the opposite experience with JSON files and sublime vs. vscode. Sublime opens fast and seamless, VSCode basically ceases to operate while it struggles to figure out syntax highlighting of such a "massive" file. I have near barebones installs of both, I do not believe it's plugins nor settings related.

Ultimately VSCode is my daily driver but I use sublime3 when I need to do fluid text editing, anything column/multi-select based, regex replaces, or manipulating large files. VScode has those features but they feel slow and buggy in comparison.

That’s surprising, in that situation my VS Code tells me that it’s turned off syntax highlighting because the file is too large.
