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?


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
