On the downloads page of Garuda Linux, they say that "we believe in the principle that unused RAM is wasted RAM". There are some performance comparisons on youtube, it wasn't well in stress tests, but opening applications was faster (Even faster than a simple Arch installation, on which it is based).
From comments there and in some other article, many suggested preloading is the reason some applications into RAM to get faster startups. I want to know what such tweaks are generally used to improve system responsiveness utilising available RAM ?
Since, we have 8GB RAM in economy range laptops too, what are the tweaks i can enable or use to provide better performance (even if by a small margin, the point is either way the RAM usage on my Arch installation is usually 2-3 GBs, if it can be used more that's a plus).
PS. For me, it's kind of "if I have a GPU, why not use hardware acceleration, instead of doing everything on CPU"
Also, I tagged tmpfs, since it also utilises RAM space instead of Disk, providing better access time, with the cost of utilising RAM.
free -mto see how much RAM is used for cache and buffers. This is what makes the system fast.
