Please link to this comment in the description

The following is based on a decompiled version of Minecraft 1.9 using MCP 9.24 beta.

The reason for this is very likely that the method net.minecraft.block.BlockChest.onBlockPlaced(World, BlockPos, EnumFacing, float, float, float, int, EntityLivingBase) is not calling the method net.minecraft.block.BlockChest.checkForSurroundingChests(World, BlockPos, IBlockState).

This might be inefficient because the method net.minecraft.block.BlockChest.onBlockAdded(World, BlockPos, IBlockState) is doing this always, whereas the method mentioned before and the method net.minecraft.block.BlockChest.onBlockPlacedBy(World, BlockPos, IBlockState, EntityLivingBase, ItemStack) do this when the chest is placed by a player, which means the same tests are done three times at the end.
