Idea for improve minecraft performance
Recently, I heard the suggestion to have a performance update. I think (and the developers confirmed it) that this update could stop the pace of Minecraft and affect the business, as well as the rest of the video game industry, which follows its rate.

Well, I propose one thing: As Minecraft updates everything little by little, when the developers update something (for example, the biomes in the Wild update or the generation in the Caves and Cliffs update), before touching anything, improve the code that doesn't have to be changed completely and thus avoid problems that could lengthen the development (as already happened with the Caves and Cliffs update).
