is a optimization mod that, by using cache and more efficient data structure, speeds up operations on common data types
Optimizations in 1.7.0:
faster Forge class scanning by skipping scanning of unused class data.
caching numeric tags (NBTs) to decrease allocation.
replace Map/Set in favor of some more efficient implementation.
better hashing for BlockPos that does better in preventing collision.
faster Industrial Foregoing JEI StoneWork recipe gathering
faster Masterful Machinery structure checking by caching intermediate results. For modpack E6E, MM structure checking can consume up to 10% of total server CPU resources, DataStructium made it 10 times faster (9.73% -> 0.81%)
(1.1.0+) "Tiered" internal for CompoundTag
(1.4.0+) Just Enough Resources spawn egg lookup is patched to be faster. Also JER has an NPE bug when loading JEI recipes, DataStructium fixed that
(1.5.0+) KubeJS Resource Cache, to prevent walking files repeatly
(1.6.0+) Farmer's Delight ToolIngredient initialization is optimized to save time wasted in creating ItemStack repeatly, and reduce memory allocation
(1.7.0+) key interning for CompoundTag backend to further decrease memory usage
(1.7.0+) Faster chunk section iterating, making client side chunk meshing and possibly other client/server chunk section-based operations faster
