Several second delay to view a folder containing several documents

I have a folder of draft content that contains 45 text documents. Clicking on the folder takes several seconds delay before displaying the grid of document info. Each time. Similar to the report https://www.literatureandlatte.com/web/forum/viewtopic.php?f=57&t=52151&p=266411&hilit=slow#p266411, it would really help the user experience to have the tree navigation be snappy.
