Parallel I/O??

Hi everyone,

Just a shot that someone might have read the same article I did. I read somewhere that there is a way to increase I/O
to IDE drives by using sysctl to set parallel I/O on or off... Is anyone familiar with this concept. If so, what's the proper
syntax for an entry in the /etc/sysctl.conf file to enable such an animal??? I'm running Red Hat Linux... on an IBM
desktop. Will gladly provide more info if needed...

Thanks,

I believe you are looking for /sbin/hdparm
# /sbin/hdparm --help

You'll see all the settings you can tweak.

# /sbin/hdparm -tT /dev/hda
will give you a quick diagnostic of throughput.
