From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

What is the proper way, if there is one, to remove files and applications added to ram with preload? (lemmy.ml)

If you're not aware of what preload is, it's a command line application that allows you to add files to ram, so they can be accessed faster by the applications that need them.

It seems to work well for what I'm using it for, which is to run games from slower storage devices, but there doesn't seem to be any documentation for a proper way to remove the files once they've been added to ram. What I've been doing is to just use htop to terminate the preload command, but I feel like this is not intended at all. Is there a better way to remove these files?

I should mention that while trying to search for a solution myself, I did see gopreload mentioned a few times. I would try this out myself, but there's no proper installation instructions, at least not any I could find that work in Linux Mint.

After trying vmtouch, it only seems to be partially helping. I'm not sure if I'm just using it incorrectly or not but if I remove the files from RAM and then use vmtouch to add them back in, the hitching issues are still partially there.

To fully explain what my issue is, I currently using the Linux version of the Cyber Lancer demo from Itchio as it's small enough to fit onto my 128 MB SD card, which is very slow. I can easily run the game from other storage devices that have much higher read speeds but I want to get the most out of my older and slower storage devices. What's happening is when the game first loads when it's files aren't stored in RAM, is the game essentially freezes for a split second every time it has to load an asset that wasn't previously loaded.

vmtouch isn't making the hitching go away, it just making it load a little faster. This does mean that it'll help but if you're aware of a better solution, I can try that out as well.
