Oh yeah, this... i can clearly remember back then when on a then mid- range machine with a lot of compiling (gentoo => 100% cpu �[U+1F923]�) and filesystem work, VLC used to play an HD video stream even under heavy load without any hiccups and micro-stuttering.. It was impressive at the time.. and then.. it broke �[U+1F928]� -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/336652 Title: Poor system performance under I/O load Status in Linux: Fix Released Status in linux package in Ubuntu: Incomplete Bug description: This bug seems to particularly affect the Dell Latitude D420, D430 and (from the kernel.org bug) at least the D830 laptop models; but others have been reported. 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.
