Probably, it is known problem. Any massive HDD operations, such a generation of |
2 |
DVD structure (or even copying files from DVD to HDD - case, when stream speed |
3 |
is limited by DVD-drive), make desktop enviroment (KDE in my case) noticeably |
4 |
"clumsy". This takes place also when an operation is initiated via CLI with |
5 |
"nice -n 10" prefix. All drives are in UDMA mode. If I remember well, this |
6 |
problem was not so obvious with 2.4 kernels. |

I use ~x86 and IDE HDD. 'hdparm -i /dev/hda' and 'hdparm -tT /dev/hda' are below. |
