lol?(Windows user perspective) Unless you run it on 10 year old hardware yes, terrible performance. Notepad is better. But if you have at least an ssd and 4gb of ram, I don't see any issues.
This is exactly why I prefer Notepad++, it's resource efficient, it doesn't matter where you run it on. Even on the Raspberry Pi the performance is quite decent.
