GregTech 7.5.3 Performance Fixes

The patch changes how GregTech machines look for recipes and how input handlers are polled. Machines track a version counter on their input handlers, and RecipeRunner caches grouped handler lists per machine so they are rebuilt only when needed. Empty handlers are skipped, and earlier recipes with contents return early, which cuts the number of buses scanned per recipe search.

Input buses and hatches that stock items now check the network less often, not on every tick. They are notified about changes through AE2 instead. Pattern buffers run one worker per proxy plus one buffer, sharing internal slots rather than holding one slot per pattern, so a machine checks fewer buses. Cover redstone polling runs every 40 ticks, which fixes covers that sometimes malfunctioned and stopped a machine.

The patch is built for GregTech Modern 7.5.3 only. It runs on Forge for 1.20.1 – 1.20.6, is open source under the GNU Lesser General Public License v3.0 only, and needs both the server and every player to be on the client and server side. It is not part of GregTech itself.
