Not in 15ish years and at the time I think I had a 5400rpm hd, so that probably limited any perception of sublime being noticeably faster than other editors I was using (geany, kate). I don't doubt that sublime is faster than vscode today, but the vscode ecosystem is a pretty nice place to be and probably worth trading some speed for, especially on a nice mac where the trade off is probably small. Zed might be even better however.
