Thread: copying files slow

  1. #1

    Default copying files slow


    I am running OpenSuse 11.1 with KDE 4.2 on an Corde2Duo 2 x 1.66.

    Copying files on the same partition to another folder is quite slow. The speed is about 15 Mb/s, even if I use the bash. So KDE can't be the problem. Filesystem is ext3.

    hdparm -tT /dev/sda retrieves

    Timing cached reads: 1008 MB in 2.00 seconds = 503.63 MB/sec
    Timing buffered disk reads: 194 MB in 3.03 seconds = 64.12 MB/sec

    and hdparm -i /dev/sda

    Is there a chance to speedup the system?

    Default Re: copying files slow

    mount your filesystems with the noatime option in /etc/fstab

    Also, if you are copying files downloaded from torrents and your client doesn't support file preallocation or it's not enabled, your files will be fragmented so copying to other places will be slower

    Your settings look good though
