Well, if you are going to write the output to disk file, the
program will even be slower, as disks are orders of a magnitude
slower than memory. If you are writing to memory, you quickly
have a problem because the large amounts of data tcpdump is
writing will quickly fill up large chuncks of memory. If it's
indeed the buffer size that is the problem, you're better off
enlarging the buffer size, by tweaking the OS.
But I expect that this is one of the cases one would prefer
to use C instead of Perl.

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).

or How to display code and escape characters
are good places to start.
