speed tip

[Jauder Ho]

I'm using a IBM TP600E with a 366 PII chip so I am trying to wring out
every last piece of performance out of this laptop in order to watch dvds.

The following is something which you can try. It did improve the framerate
by several frames per second for me. YMMV. I am averaging around 20fps
using the default size right now.

[root at turtle linux]# cat /proc/ide/hdc/settings

I set the file_readahead and current_speed.

[root at turtle linux]# echo file_readahead:2000000 >/proc/ide/hdc/settings
[root at turtle linux]# echo current_speed:69 >/proc/ide/hdc/settings

Looking into the other params right now...
