Any advice for Multiplayer optimizations?

I’ve been working on a tps battle royale project and have been using Mirror as my primary networking tool. However, I recently discovered that Mirror isn’t the most optimized option for this purpose.

On the other hand, I’ve heard about Unity’s new netcode for entities, which can support hundreds of players simultaneously.

I’m curious to know what Reddit users think about migrating from Mirror to this new netcode. I understand that it’s a significant undertaking, but I believe it offers a more robust and efficient solution in the long run.
