First of all, without specifics it's hard to give you any but general advice. With specifics I mean, how does your perlcode look like?

Perl is a memory eater. But in my experience you only get to these huge amounts of memory footprint if you have large data structures holding small items. Eg, a million array items of one byte will take 43 Mb of memory. Array but more so hash overhead is large.

To me it sounds like you are trying to rebuild your PostgreSQL database in perl memory. That would be a bad idea. If this is the case and if you did so because Postgres communication is too slow (I doubt that with 10/s) move to a faster system, like BerkeleyDB (www.sleepycat.com).

About the malloc system, perl normally comes with its own. If you want to know more about it, read perlguts.

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.
