This is a really small mod that may or may not help your KSP loading reach hyperspace for HDD users. It worked for a small sample of tester and the result are more likely tied with how fast your disk are and how much memory you have (if you have 16GB of ram this should not help the 2nd loading because the game will most likely be cached)

How to properly test if things are faster. Launch the game twice up the main menu without the mod installed (one to cache things a bit, then to measure). After the second launch open the KSP.log and search for the "Loading Systems: Elapsed time is 29.1946s" line.

Then install the mod, launch and look at the line again and tell me if it did anything for you. (if you have ModuleManager it will rebuild the cache on the first launch so you will have to launch twice...)

Download for KSP 1.4-.1.7

I run a pretty slim install because modding means restarting KSP frequently.  But let's have a look here. 

Before: Loading Systems: Elapsed time is 55.90594s
After:  Loading Systems: Elapsed time is 45.87465s

10 seconds is huge, so thank you, sir!!!

But...  it doesn't come with any hypercats.  Why are there no hypercats?

Thx, great mod. :)

I usually preload GameData and KSP_x64_Data into RAM-Cache with this tool and the batch file in the spoiler section.
Then run it 1 or 2 times, to have the modulemanager patches cached. (200 Mods)
When loading it then, KSP loads without noticable HDD activity ( so 99% from RAM-cache).

And even that good prepared startup Hyperspace can speed up:
[LOG 01:07:05.741] Loading Systems: Elapsed time is 279.3334s
[LOG 01:14:19.143] Loading Systems: Elapsed time is 200.1533s
(both times modulemanager loaded the cached version - no patches)

Nice! :)
BTW, wonder how that works?!

How does that work from the coding side? Whats the principle behind it? Saw some assembler in the code.

The IL assembly is the black magic part. What the mod actually does is switching the constructor code of mono BinaryReader with my implementation that just add a BufferedStream before the reader.

Edit: I am sure it could be made even faster but it get complex fast :)

System: Windows 10 64bit, 32gb DDR3, 1TB SSD

Just to make sure I did this right, the .dll file goes into the Gamedata folder, yes?

Interesting! I tried doing as you said there with the folder cache, but did not see any real improvement on my load time.

That said, i'm not 100% sure I did it correctly either. I installed it, right clicked and loaded the gamedata and 64_data folders into ram, then launched the game twice. The bit you mention about a batch file kinda lsot me :(

WOW  !!!

Are you sure there wasn't some file caching also going on there?  Most OSes cache files in RAM if you have enough spare, so loading KSP the 2nd time will always be faster if you haven't done much else in between.
