To be clear, by "Centos 7 installation", I meant a PC on which Centos 7 was installed.
In any case, Centos 7 has not always been this slow. Presumably something has changed. I've been living with this for several months, but not forever. I can run compilers and stuff without an internet connection, so I could get some work done.
To get that output, I had free running in a loop and waited for the freeze before copy and pasting.
I wasn't surprised by the result. Occasionally top shows kswap0 (I think) in a D state.
Does the system slow down when you have your internet connection enabled, but aren't explicitly using it (i.e., not using a browser)? If so, look at the netstat output (as root) to see what's going on. You may have some process that runs when the connection is enabled that is taking up system/network resources.
Separately, turn off javascript in the browser you are using and see if that has an effect.
