I have extremely high "free memory". According to this site here it is better to have "free memory" as close to 0 as possible. What I understand is that this "free memory" is basically wasted memory as it is not being used at all.

If that is the case, how can I "release" this free memory or utilize this free memory? See below the free memory when I use top (typically it is much, much higher):

MiB Mem :   7829.3 total,   2952.5 free,   1766.8 used,   3110.0 buff/cache
MiB Swap:   2048.0 total,   2047.7 free,      0.2 used.   5727.4 avail Mem 

FYI, I am using Xubuntu 19.10, Dual-boot with Windows 10, Core i5 2.5GHz if that helps.

    The site explicitly says free memory will approach 0 after running for a while. You should run free -m (after some usage, the heavier the faster you will use memory). That being said, there is no reason why a lightly used system should use tons of memory if it is not doing much and what it does deals with the same buffers over and over. – Eduardo Trápani May 12 '20 at 2:50

    Free memory will eventually be used in the "used" or "buff/cache" figures. Nothing is wrong here. – heynnema May 12 '20 at 14:18
  • @EduardoTrápani yep that's right. missed that part. i will take your advice and keep an eye on the usage. thanks! – TheButcherOfBlaviken May 12 '20 at 18:44
