Making things run faster

I am processing some terabytes of information on a computer having 8 processors (each with 4 cores) with a 16GB RAM and 5TB hard drive implemented as a RAID. The processing doesn't seem to be blazingly fast perhaps because of the IO limitation.

I am basically running a perl script to read some data and then either modify it a little or grep something out of it and writing it back to disk. Could someone please tell me if there is a superior method I could use to improve performance?

play_sample(3alleg4)						  Allegro manual					      play_sample(3alleg4)

NAME
play_sample - Plays a sample. Allegro game programming library. SYNOPSIS
#include <allegro.h> int play_sample(const SAMPLE *spl, int vol, int pan, int freq, int loop); DESCRIPTION
Triggers a sample at the specified volume, pan position, and frequency. The parameters `vol' and `pan' range from 0 (min/left) to 255 (max/right). Frequency is relative rather than absolute: 1000 represents the frequency that the sample was recorded at, 2000 is twice this, etc. If `loop' is not zero, the sample will repeat until you call stop_sample(), and can be manipulated while it is playing by call- ing adjust_sample(). Example: /* Scream from the left speaker, twice the freq. */ int sound = play_sample(scream, 255, 0, 2000, 0); RETURN VALUE
Returns the voice number that was allocated for the sample or negative if no voices were available. SEE ALSO
