OwehSMP

This optional mod pack was explicitly made for the OwehSMP.

This mod pack contains mostly performance improvements,

• Such as Sodium, which dramatically modifies Minecraft's rendering engine to increase average frame rates reportedly between 250% to 500%.
• Or FerriteCore, which reduces the amount of memory—or RAM—by making minor changes to how the game caches or holds onto certain data that isn't necessary or being used at the moment.

...and Optifine-esc changes,

• Such as connected textures from Continuity
• And a spyglass-esc zoom hotkey with Zoomify.

But, the most notable change is the voice chat functionality from Simple Voice Chat.

This allows players to hear each other speak in-game based on their player's proximity to one another. Sculk sensors and the Warden will also react to your voice!

It also introduces players to the ability to create custom music discs based on audio files they suggest be added to the server.

The tutorial also provides the basics on how to use voice chat in-game.
