The persistent.sfs

[gamerscircle]

I was told that KSP loads in the entire persistent.sfs file into memory.

is this still true?

[Duck McFuddle]

Short answer: yes.

Long answer: yes, and I noticed this as well.

It does... but that isn't a problem as even a large persist (I have one with 72 ongoing flights right now and it's only 10MBs in size. Something even a computer from 2002 can handle as it's a relatively small file to load into memory. Sure, Squad could set it up so it only loads relevant chunks at a time, but you'd only gain 10 measly megabytes to work with. Even by Unity's standards, that isn't very much.

Doesn't it come down to how much other stuff loads in response to loading the file more than the file itself?
