How to remove lag in RecyclerView?

Question

Kotlin

I have a RecyclerView with a lot of data and each ViewHolder has its own very heavy ViewGroup (list of tags + list of categories) because of it it slows down a lot because when scrolling the RecyclerView it redraws my ViewGroup and forces the user to see micro-freezes. What to do and what are the solutions?
