Output of "hdparm -I ..." is attached. The machine can be accessed only remotely at the moment, I can't check removing the DVD, but I think it's totally another bus so it shouldn't cause problems. Also please note that eg copying file from a file through the network is quite OK. The slowness can be seen if there are concurrent I/O requests when the whole machine is painfully slow. One I/O itself (like otherwise idle machine and copying a file by sequentially reading it and eg streaming it through the network) is OK (in speed) but any other task is painfully slow, mouse cursor stops for seconds, if I try to execute even a plain 'ls' command it can wait for seconds or even more, etc. Also, I know it's hard to define as a problem, but I feel this issue is becoming more and more serious one with every newer ubuntu versions, but I know it's quite subjective thing to just say. Thanks. ** Attachment added: "hdparm.txt" http://launchpadlibrarian.net/17595063/hdparm.txt -- Disk I/O is very slow, system freezes for seconds https://bugs.launchpad.net/bugs/268588 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
