Granted I don't know why you have both high idle and low i/o wait, but my eye is attracted to this part of your post:

"...and prints the line back out to another file on the same disk."

Is there any way you can have the input and the output files on separate volumes (or strings)? You might have faith in the machine's RAID setup (assuming there is one), but it's not guaranteed to save your bacon. Give it a try, even if the input (or output) has to be in a different part of a LAN.

Are you posting in the right place? Check out Where do I post X? to know for sure.
Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
Want more info? How to link or How to display code and escape characters are good places to start.
