Clear device cache if you haven't already:

1) Turn off your device.

[Your device may need to be connected to a powered USB device (ex: computer) before proceeding to the next step.]

2) Press and hold the Volume Up button and the Side/Power button until you feel a vibration and the Samsung logo appears. Let go of the buttons.

3) You will now be in Android recovery. Use the Volume buttons to highlight "Wipe cache partition."

4) Press the Side/Power button to execute.

5) Use the Volume buttons to highlight "Yes."

6) Press the Side/Power button to execute.

7) "Reboot system now" will already be highlighted. Press the Side/Power button to execute.

Samsung's Good Guardians app provides additional tools to re-optimize your device. This can be particularly helpful for previous-gen devices that have recently been updated.

Yes, do as @CEParsons suggests and download Good Guardians and the App Booster module.  It works similarly to Windows defragmenter.  It will put your apps back together and optimize them all.  You should see better performance after running it.  You should run it after every system update and any time you notice degraded app performance.
