VMTouch may be helpful. https://hoytech.com/vmtouch/
Just lock the file into memory using:
```vmtouch -l /path/to/binary```

You're claiming that gnome loads all of itself into memory so that it can be faster. Now there are a few reasons why I don't think that's a reasonable idea, but assuming that you wanted that... using techniques like vmtouch to keep the files in the disk cache would make it so that gnome wasn't actually using the full 1GB. The "cached" files could be evicted from the cache if some other program needed that memory. Where as loading all of gnome in at startup regardless of whether it's actually used is probably not a good idea.

What's limiting PC RAM size?
It is a mainstream thing. It's enabled by default on every Windows install, as far as I know, although you may not be impressed by its understanding of what your frequently opened programs are. It's been about ten years since I ran Windows, but I used to have a batch script to read everything in a directory so that it would be in the disk cache and subsequent accesses would come from RAM. The Linux equivalent of my script is vmtouch, although that's a lot more full-featured.
