Since quite a bit I noticed that centos 7 takes too much to load for a Linux system. I have a Dell Inspiron 14 and I only have Centos 7 installed. It was never that much fast since the installation of Centos, but nowadays it just gets more slow. Even after the system finally loads it keeps being slow, If i open a terminal, it takes some time before I get the prompt to be able to write. Firefox also has this issue, opening a chat window in FB or changing from one chat to another in whatsapp web, even changing from one tab to another takes some time. Let me show you all the details of my system. I hope someone can help me with this
The disk filesystem is like this:
