Looking around I found this bug: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/343371
He talk about reading big files, so I make some test and I found out that I have this problem too, even with noop: This time (just reading a big file from a sata disk, not using a pendrive) the system become really unusable! On the home pc, where I never seen problem writing large file using CFQ, I don't have this problem too. so, may be it's not a scheduler problem, but something else, and changing the scheduler just alleviate the problem... Is it possible? How can I find out if it's a latency problem as described in 343371? -- elevator=cfq (default) cause starvation https://bugs.launchpad.net/bugs/381300 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
