Thank you for all the people answer my doubt.
I decided, I will add more ram like @bob466 say
@KGIII I saw, I use edge browse for study so I edit PDF on it.
I decided also desactive swap while I dont have enought memory
and how I close this thread?
okay, my pc is Celeron 3865U with 4G ram and 512gb HDD, I put 2gb as swap in my pc but usually my swap memory fill up, I dont know how i resolve it
I try change swappiness for 10, but nothing happened. someone else know resolve?
