RecyclerView Scroll Slow - setHasStableIds not working, possible to preload more than one offscreen views?

I have been trying to fix my slow scrolling in a Twitter like app using RecyclerView by using the suggestions from this [link][1] and have had trouble with #7 "setHasStableIds(true)". When I don't override getItemId(), I only get about 6 items in my RecyclerView out of 30ish. When I override it and return position or the tweetStatusID for the function, it still lags like when I wasn't using setHasStableIds(true) for my adapter.

UPDATED: I have added some AsyncTasks which has improved my speed but it's still slow, I was curious if any more improvements can be made or if it's possible to preload more views so more are ready when scrolling fast.

MyFeed onCreate():

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_feed);
final RecyclerView recyclerView = findViewById(R.id.rv_feed);
RecyclerView.LayoutManager layoutManager = new LinearLayoutManager(getApplicationContext());

DatabaseReference databaseReference;

// Create new Twitter configuration
ConfigurationBuilder cb = new ConfigurationBuilder();

// Create Twitter instance for retweeting
TwitterFactory tf = new TwitterFactory(cb.build());
twitter = tf.getInstance();

authTokenToken = getIntent().getStringExtra("AUTH_TOKEN_TOKEN");
authTokenSecret = getIntent().getStringExtra("AUTH_TOKEN_SECRET");

// Firebase Auth
mAuth = FirebaseAuth.getInstance();
dbFeedPath = getResources().getString(R.string.isu_feed);
databaseReference = FirebaseDatabase.getInstance().getReference(dbFeedPath);

databaseReference.addValueEventListener(new ValueEventListener()
{
  @Override
  public void onDataChange(@NonNull final DataSnapshot dataSnapshot)
  {
    AsyncTask.execute(new Runnable()
    {
      @Override
      public void run()
      {
        listFeedList.clear();

        for (DataSnapshot postSnapshot : dataSnapshot.getChildren())
        {
          TweetData tweetData = postSnapshot.getValue(TweetData.class);

          if ((tweetData != null) && (!tweetData.tweetText.equals("")))
          {
            TweetData listTweetData = new TweetData(tweetData);

            listFeedList.add(listTweetData);
          }
        }
      }
    });

    mAdapter.notifyDataSetChanged();
  }

  @Override
  public void onCancelled(@NonNull DatabaseError databaseError)
  {
  }
});


mAdapter = new TweetListAdapterFeed(listFeedList, this.getApplicationContext(), new ClickListener()
{
});

mAdapter.setHasStableIds(true);
recyclerView.setHasFixedSize(true);
recyclerView.setItemViewCacheSize(20);
recyclerView.setDrawingCacheEnabled(true);
recyclerView.setDrawingCacheQuality(View.DRAWING_CACHE_QUALITY_HIGH);
recyclerView.setLayoutManager(layoutManager);
recyclerView.setAdapter(mAdapter);
