That's an unusual experience. Based on a handful of benchmarks[0] done by the author of JOE, VS Code is sometimes an order of magnitude slower than Notepad++ and Sublime at some tasks.
I use VS Code pretty much exclusively these days myself, so I'm not picking on it by any means.
I have the same experience on my pretty slow laptop. Granted, my projects aren't big, but I would take vs code over sublime any day. Interestingly, atom feels much slower compared to both.
