Subject: [PATCH] Improve performance of mass crafts
When the server crafts all available items in CraftingMenu or InventoryMenu the game
checks either 4 or 9 times for each individual craft for a matching recipe for that container.
This check can be expensive if 64 total crafts are being performed with the recipe matching logic
being run 64 * 9 + 64 times. A breakdown of those times is below. This patch caches the last matching
recipe so that it is checked first and only if it doesn't match does the rest of the matching logic run.
Shift-click crafts are processed one at a time, so shift clicking on an item in the result of a iron block craft
where all the 9 inputs are full stacks of iron will run 64 iron block crafts. For each of those crafts, the
'remaining' blocks are calculated. This is due to recipes that have leftover items like buckets. This is done
for each craft, and done once to get the full 9 leftover items which are usually air. Then 1 item is removed
from each of the 9 inputs and each time that happens, logic is triggered to update the result itemstack. So
for each craft, that logic is run 9 times (hence the 64 * 9). The + 64 is from the 64 checks for remaining items.
After this patch, the full iteration over all recipes checking for a match should run once for a full craft to find the
initial recipe match. Then that recipe will be checked first for all future recipe match checks.
