On my system I get a crazy high load that stutter my system and sometime also it hung. For example if I copy a big file from a usb hdd to my internal hdd i get and average load of 6-7, if I dd from my hdd to a sd card i get an ever worst load. If my system swap I get a load of 10-11. As result my system is unusable as soon it start to do some io.
I already changed my internal hdd with a new one so it is not a hdd issue.
toshiba satellite pro l650
1TB toshiba hdd
intel i5 first generation
Do you have any suggestions?
