You can change the readahead-buffering on linux on 2.4 through the proc 
file system.  Under 2.6 it might have moved to the new sys interface.

2.4:

	/proc/sys/vm/max-readahead

Set it to a power of 2 - 1.  I can't remember the units.  It defaults to 
31 on 2.4.  If you want to allocate more memory just:

	echo 63 > /proc/sys/vm/max-readahead

and try it out.  If you want to make it permanent on a redhhat box you 
can add it to your /etc/sysctl.conf
