MicroOptimizations
Players on Minecraft 1.8.9 who want a lighter client can add MicroOptimizations, a Forge optimization mod released under the GNU Lesser General Public License v2.1 only.
What it does
MicroOptimizations targets small performance costs in the 1.8.9 client, and its page presents it as a set of micro-level changes rather than a single large rework. Because it changes nothing on the server side, a multiplayer server does not need it, and players can add or remove it on their own without affecting others on the same server.
Key features
Client-side tuning
Changes are applied on the client, where the game spends time on rendering and logic that the author tuned for 1.8.9.
Micro-level changes
Small, targeted adjustments replace broad rewrites, so each change touches only a narrow part of the client's work.
Public source code
The source is published for anyone to read, modify and redistribute under the terms of the license.
Compatibility
Latest build for each game version and loader.
Only full game releases are shown. This mod publishes no snapshot builds.
How it compares
Velox Caelo is also a Forge client-side mod for 1.8.9, but it is released under All rights reserved, so its code is not open source. Relictium is an open source Forge client-side mod under the GNU Lesser General Public License v3.0 only, built for 1.12.2 rather than 1.8.9.

What the author says
FeatherClient has made some of their optimizations public at FeatherOpt. I ported the optimizations that do not already exist in other Forge 1.8.9 optimization mods here to work on regular Forge. These optimizations are mostly cache and block pos pooling improvements. For further optimizations, I recommend using…
