Re: VIA IDE performance under 2.6.0-test7/8?

Problem solved ...

I wrote that playing around with read ahead settings (hdparm -a ...) did not help.
In fact I was wrong, I assumed that these had identical meaning in the 2.4 and
2.6 kernel series and tried nothing higher than 255 (2.4.x maximum). With 255
kernel 2.4.0 performed 50% better than 2.6.0.

After hdparm -a 8192 /dev/hd?: 2.6.0 performs 10% better than 2.4.0

Shouln´t the default settings be corrected?
