Too much HDD activity after upgrade

[attila_66]

Hi All,

I upgraded my system from Saucy. (AMD Phenomx6 1090T + Ati Radeon HD6790)
After upgrade there is too much HDD activity. HDD led always on and system sometimes goes too slow.

Any idea to resolve this issue?

I think that the reason is the same as here: https://www.kubuntuforums.net/showth...ng-performance

The easy way to find out what is causing it is to look at System Activities, started by simultaneously pressing Esc+Ctrl.

Click CPU and Memory to find out what is running amok.

You could also use HTOP and sort it's output by IO_RATR to see which process(es) are being disk piggy.

On the command line also, lsof lists open files, and which process has them open.
