Ipad Storage Loading Problems

I have used less than half the space available on my iPad pro, and yet it takes about 2-3 minutes to load everything. And once it does load everything, it freezes for 10 seconds every 5 seconds. It is getting really annoying trying to go through my system memory when I can't scroll for 5 seconds without it freezing on me. Not to mention that I have to wait 4 minutes for it to open in the first place.
