How max handles abstractions/RAM/HD

hi list !

i have a huge patch, calling a lot of abstractions. i takes several minutes to load.

i was wondering how max handles subpatches and abstractions. does max will access hard drive each time an abstraction is loaded to read the original maxpat file, or will max be smart enough to store it in ram the first time it loads and then reload other calls from ram without accessing the hard drive ?

i'm trying to speed up my application start time.
