I'm on mobile so I'll keep this short but I found this[0] a long time ago and it still seems to work. It uses strace, mmap, and mlock to load any program you want and it's libraries, etc. into RAM but only those programs so if you're short on memory, no problem. During the setup, you can even mouse around in the program and preload anything involved in that. Back in the day I used it on really slow stuff like OpenOffice, Firefox, GIMP, etc. and it sped the opening of those programs significantly. The great thing, again, is you set it to preload only the specific things you need into RAM and nothing you don't. And, once done, it's pretty much set and forget.
