Created attachment 282483 attachment-22369-0.html Well, I've tried to report a new bug to investigate my own "my CPU does nothing because waiting is too hard for it". Of no interest of any kernel dev. So, just as Linus once said "f**k you Nvidia", the very same goes back to linux itself. Pity some devs think that make their software linux-bound (via udev only binding or alsa only sound out) is a good idea (gnome and even parts of KDE). They forgot 15 years ago they picketed Adobe for having flash for win only. Now one has to use 12309-bound crap for not having a way to run his software on another platform.

Under I/O load, which need not be excessive - running usb-creator or even just checking one's email - the system performs remarkably poorly, far less than other laptop users see. It can often take minutes to open a window, and sometimes the screen isn't repainted. Certainly most applications are "dimmed" by Compiz under I/O. It also appears to massively negatively affect boot performance, with one core spending its entire time in I/O wait - something we don't see elsewhere.
