Ok. I tried to increase speed of IO operations by setting Promise ATA100 controller, both IDE drives worked in ATA100 mode but speed also was fully CPU depend and 2.7-3MB/s. Also copying in network or /dev/null made same speed. HDD was connected in different channels of controller. Using 6.0 current not give me more performance. My kernel configuration is GENERIC with some USB devices (ucom,umodem...), without IPv6 and some unused NIC drivers. Also i seen DMA-READ errors with 5.x and 6.x with HDD, but with old 4.x it never took place. -- Best regards, Andrey mailto:samspeedu@mail.ru
