My Raspberry Pi 2 Model B Running Kali Really Slow

Hello! I have installed Kali Linux on my Raspberry Pi 2 model B. I chose Kali Linux RaspberryPi 2 and 3 as you can see on this picture.

Next, I copied this image to my SD card (32 GB) and installed Kali on Raspberry. Everything was fine till I started doing something. When I am opening apps it is insanely slow, can't do anything on that.

Please help me, I don't know what to do.

Thank you for your advises and time.
