I'm still not sure if i really understand what you want.
For example: more better and faster loading million object in array lists.
can not handle millions of objects at the start to be a long, other projects and even more games load more quickly, and objects.
QuoteGT is allready as optimized and multithreaded as possible. It is just so much bigger than other mods
this is not enough. Looking at the result - we have to work on the code and work. Do not user should wait for 3 minutes or more to any processing of mod, he should not see them at all. Maincraft runs without forge much faster than this mod for example.
