Mass Crafting Lag

Playing FTB Unstable 4.1.1 (Refined Storage 0.8)
Possibly Related to #122, it is unclear if that ticket refers to autocrafting only or not.
For example assume the player wants to craft a stack of chests. In a RS crafting grid you can put 8 stacks of planks arranged in a the right pattern and shift click the result to craft a whole stack instantly. However if you put your 8 stacks of planks in RS and in the grid only put 1 plank in each slot and shift click the result, the server process seems to come to a halt for several seconds. The GUI is unresponsive and nothing appears to happen. The client seems to stay alive and does not lock.
I believe what is happening is for each item in the grid RS is searching the attached storage for matching items and withdrawing one item. It does this 8 times to complete the pattern, and then continues on to repeat 64 times in order to make a complete stack. I assume the search for items is expensive and repeating it 512 times (8x64) exacerbates this expense.
The RS system in my play testing has 3 disk drives each full of 1k storage cells and are about 70% full of various items overall, with around 425 unique items.
I got the 0.8.5 update today and that seems to fix this issue. As this issue is still open I'm not sure if the fix was intentional or not....
Completely forgot about this issue. >=0.8.4 got massive performance improvements, so yeah, that would indeed cause a fix. :D
