[Kernel-packages] [Bug 131094] Re: Heavy Disk I/O harms desktop responsiveness
In my case ( see https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1460985 ) the culprit generating huge I/O throughput was in /etc/cron.daily/man-db It's such a long-standing and persistent bug that the default advice I give nowadays to people complaining about their ubuntu "got stuck again" is to run "sudo killall -9 find". That's really a shame: - it's not some random IO spike coming from nowhere - it's not 3rd-party, it's in default install - it's reproducible Yet, we still don't even have workaround, let alone proper policing IO of all the background tasks shipped in default ubuntu install.
