I find that VSCode's performance is not really poor, most of the time. VSCode is actually faster to open large files. Yes, it's true, compare it yourself! I have definitely experienced performance issues in Sublime with long lines as well. My performance problems with VSCode are mostly short hangs and trouble keeping up with typing. Sublime is definitely better, but I only experience those problems in VSCode sometimes. And I could probably fix it by removing some of the extensions I have installed.
