Andy Young, an ex-Microsoft senior software engineer, posted a message on X/Twitter bemoaning that even with his $1,600 Core i9 CPU and 128 GB of RAM, Windows...
I’m sorry but low RAM usage is not good performance, those are not the same.
Also, I’ve read somewhere that all memory not in use is wasted memory. I find that thought really interesting. If an operating system would be able to always maximize RAM usage by loading every peace of software and information it uses or is about to use without using swap or a pagefile it shoud be more responsive I think.
linux is caching a lot, if there’s enough RAM. you can see it in the output of the “free” command.
however, nothing stops you from moving all the stuff you frequently use to a ramdisk. it’s just uncomfortable copying it over and refreshing it as updates come in. also you may want to persist some files.
personally i have my shader caches on a ramdisk on some of my boxes. the gains are minimal.

mount /dev/vg-ssd/lv-usr /usr
But do it during install or you have to go behind and remove the eclipsed install stuff after.
And don’t do it on systemd-afflicted systems as lennart’s cancer makes that harder because he couldn’t figure out why a /usr directory was useful and he ditched it. Dunning-kruger says what?

Yes, you are right. But windows load programs Into ram that I don’t even want to use.
In addition to less ram usage thee is also less CPU usage and faster boot time (with HDD).

/usr was introduced because the original UNIX machine ran out of storage space and they had to mount a second drive.
I just memeory leak and gain infinite performance /s
