System Is Not Using All Available RAM.
by dptzippy from LinuxQuestions.org on (#5EYVZ)
Hello! I hope I am posting this in the correct section. I have built my own distro, based (initially) on LFS, but I have since spent countless hours expanding its usefulness. That being said, I can generate reports/logs, as long as somebody can tell me what programs/packages to use (I am still kind of new to Linux).
Today's issue comes from my system being incredibly slow, despite having (IMO) pretty good hardware. At the very least, I would expect that 32GB of DDR4 RAM (I can't remember what the frequency is), and a 10th gen i5 processor could keep up with literally just an empty AbiWord window, a Konsole window, and XFCE (with nothing running). I checked system stats, and I noticed that none of my 12 cores came under even 3% usage, and my disk usage stayed below 10% (I was using wget to download a directory), yet memory usage was consistently at 99%.
I would think my system is at fault, given that I built it, but I have no issue running games, browsers, tons of tabs, stuff in the backround, etc., so this whole issue must be from something in the operating system. I saw wget was using ~95% of memory, so I killed it, but given the aforementioned 32GB of DDR4, I really shouldn't have to, especially when it seems to work when in the shell.
That being said, how can I check if my system is using all available memory? I boot into my OS, so I don't need to save any for a host system or anything. Thanks for the help!
