Here is the benchmark test I ran. There seems to be a non-negligible difference, but it isn't big enough to worry about unless you are trying some sort of highspeed realtime application. I didn't do any printouts, to be fair.
#!/usr/bin/perl use warnings; use strict; use Benchmark; my %bighashname; my %b; timethese(10000, { hashbigname => sub { for(1..1000){ $bighashname{"bighashval$_"} = $_ } for(1..1000){ $bighashname{"bighashval$_"}++; } }, hashsmallname => sub { for(1..1000){ $b{"b$_"} = $_ } for(1..1000){ $b{"b$_"}++; } }, }); #Benchmark: timing 10000 iterations of hashbigname, hashsmallname... #hashbigname: 39 wallclock secs (39.27 usr + 0.00 sys = #39.27 CPU) @ + 254.65/s (n=10000) #hashsmallname: 35 wallclock secs (34.66 usr + 0.00 sys = #34.66 CPU) + @ 288.52/s (n=10000)

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.
