UsefulMods VS MohistEssentialsX

There's tons of mods that do what Optifine did now. https://github.com/TheUsefulLists/UsefulMods

You can try Java tweaks - https://github.com/brucethemoose/Minecraft-Performance-Flags-Benchmarks or performance mods - https://github.com/TheUsefulLists/UsefulMods

Reference this list of performance mods, find your version, and ensure you're using as many as possible (as long as 2 don't conflict.)

Just an FYI, that list has been archived and is no longer being maintained. Use this instead: https://github.com/TheUsefulLists/UsefulMods

I think you can see it in different ways (Do not trust Essentials' PSA "Do not use mohist"), but I prefer to know what I am running. The idea to replace files with compatible ones is a security issue, but I admit I would have done it the same way if I ran into this problem. My bigger problem with Mohist is the mentality, eg. that they tried to change Essentials' PSA into an ad (Pull Request - Reference). But I think, if mohist works well for you, and you (if possible) do not replace the plugin jars by Mohist's, it is okay to use. It is just something you should be aware of.

By the way if you want more information about what EssentialsX said about Mohist, I invite you to read https://github.com/Shawiizz/MohistEssentialsX/blob/main/README.md.
