Adobe Photoshop 23.5.1 extremely slow

Dear Adobe, 

Please hire some new talents to rewrite Photoshop's code. Now I am switching back to Photoshop 2020 so I can use it. With every new release it gets slower and slower... A simple task like gradient on a mask, or just applaying some median blur - it takes ages....not fun. I already have switched off using the graphic card (it did not help). I use it on a IMac with 64 ram, 8gb amd radeon and 3.8 quad-core intel i5. On the same machine I fire up Houdini and run it smootly (both simulations, modeling and render). How is it possible for an application that is 10 times heavier to run faster and smooter than Photoshop???!! hint (maybe its the code)

It is a simple suggestion and I am sure that I am not the only one experiencing this.
