Performance Tuning

[Kenny Lussier]

Hi All,

This should be a fairly easy one for someone out there.... I have made
some modifications to a system for performance reasons. One of the
changes that I made was setting the read_ahead_kb value to 1024 (up
from 128). I used the blockdev command to do this (blockdev --setra
2048 /dev/sdb). My question is, how do I make this persistent across
reboots??

TIA<
Kenny
