Sluggish behavior in the scroll for large dataset

Tested sample app with the following data:

private static final int SPAN_SIZE = 3;
private static final int SECTIONS = 50;
private static final int SECTION_ITEMS = 200;

This is because there are to many visible cells at the screen
and RecyclerView recycled view cache is too small.
You need to optimize recycled view cache size using
RecyclerView.getRecycledViewPool().setMaxRecycledViews

For example try to add following:
mRecycler.getRecycledViewPool().setMaxRecycledViews(0, 50);
mRecycler.getRecycledViewPool().setMaxRecycledViews(1, 50);

This should fix scroll speed. The only problem that viewType must be
internal. So if you have multiple item view types, you need to
calculate final viewType.

@Codewaves I tried as per your suggestion but the improvement is not visible.
