It depends on what specifically you find slow about VSCode. In my experience, some aspects of VSCode feel less responsive than Sublime simply due to intentional design choices. For example, VSCode's goto files and project symbol search is definitely not as snappy as Sublime's. But this difference is due to VSCode's choice to use debouncing (search is triggered after typing has stopped) as opposed to throttling (restricts function execution to a set time interval).
