Questions about optimizing my setup

I have a Raspberry Pi 3B, rinning LibreELEC 7.0.2 and Kodi 16.1.

I am running “MEDIUM” overclock profile.

I have read up on overclocking, and my general take away is I don’t NEED to overclock any further.

I am wondering what settings I can change for further optimization. I primarily use it for streaming video from internet streaming services. I plan on also adding the capability to play ROMs.

I have no real issues that need solved, just looking to dot the i’s and cross the t’s
