Ubuntu 14.04 - how to less ram usage
Hello,
I have an ubuntu14.04 installed pc with 32GB ram.
Code:
Operating System: Ubuntu 14.04.5 LTS
Kernel: Linux 4.9.148-xxxx-std-ipv6-64
Architecture: x86_64

When I check free memory it shows:

Code:
            total       used       free     shared    buffers    cached
Mem:         31882      31597        285       2136        135      28321
-/+ buffers/cache:       3141      28741
Swap:         4093          0       4093

I suppose there is no adequate free memory to run new applications.
If yes, how may I run more process with less ram usage.
Active processes are php, ffmpeg and mysql.
There are many sleeping process also.



PS: While searching for the answer, I've found this:

Quote:
A healthy Linux system with more than enough memory will, after running for a while, show the following expected and harmless behavior:

free memory is close to 0
used memory is close to total
available memory (or "free + buffers/cache") has enough room (let's say, 20%+ of total)
swap used does not change
Warning signs of a genuine low memory situation that you may want to look into:

available memory (or "free + buffers/cache") is close to zero
swap used increases or fluctuates
dmesg | grep oom-killer shows the OutOfMemory-killer at work
So, in my case, it's okay. No need to worry about that.


Thanks in advance
Boris
