Disk goes to sleep

Recommended Posts

I installed cooker on a usb flashdisk (ext2) and everytime I do some intensive file operations like urpmi, processes in ksysguard say disk sleep.

 

I see a package being installed, which goes quite fast and then the next one takes ages to continue and so on, all the while when waiting seeing usb-storage and urpmi in disk sleep state

 

 

 

I bought the flash disk asking for the fasted (and most expensive) and it said it was readyboost ready.

 

in ps aux the states are listed as D+ and D<

a test using smart to show the states:

 

$ ps aux | grep D 

USER	   PID %CPU %MEM	VSZ   RSS TTY	  STAT START   TIME COMMAND
