This all depends on how much you are exactly storing in your hash tables, but this code should give you a hint, just run it and watch top or some other resource monitor:
#!perl -w use strict; $|=1; my (%a,%b,%c); for (0 .. 500_000) { # set higher if you dare $a{$_} = "x" x 60; # 60 character string $b{$_} = "x" x 60; $c{$_} = "x" x 60; print "\rrow $_" unless $_ % 10000; }

note: this goes up to 190 mb for about 500_000 iterations on my machine YMMV.

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":



  • 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.
