A new benchmark trying to measure only the effect of the data structure being used. No need for further comments except that it is an entirely different benchmark:

use strict; use warnings; use Benchmark qw/cmpthese/; my @translation = qw / Zero One Two Three Four Five Six/; my %trans = (1 => "One", 2 => "Two", 3 => "Three", 4 => "Four", 5 => " +Five", 6 => "Six"); my @dispatch = ( sub {return "Zero"}, sub {return "One"}, sub {return +"Two"}, sub {return "Three"}, sub {return "Four"}, sub {return "Five" +}, sub {return "Six"} ); sub test2 { my $var2 = shift; return ("One") if ($var2 == 1 ); return ("Two") if ($var2 == 2 ); return ("Three") if ($var2 == 3 ); return ("Four ") if ($var2 == 4 ); return ("Five") if ($var2 == 5 ); return undef; } sub test3 { my $var2 = shift; return $translation[$var2]; } sub test4 { my $var = shift; return $trans{$var} ; } sub test5 { my $var = shift; eval { goto "_$var" } or return "Other"; _1: return "One" ; _2: return "Two" ; _3: return "Three"; _4: return "Four"; _5: return "Five"; } sub test6 { my $var = shift; return $dispatch[($var)]->(); } cmpthese( -1, { _linear_2 => q {test2("5")}, _array => q {test3("5")}, _hash => q {test4("5")}, _goto => q {test5("5")}, _dispatch => q {test6("5")}, } )
And the results:
$ perl test_if.pl Rate _goto _linear_2 _dispatch _hash _array _goto 1247485/s -- -17% -26% -50% -52% _linear_2 1509714/s 21% -- -11% -40% -42% _dispatch 1688450/s 35% 12% -- -33% -36% _hash 2513434/s 101% 66% 49% -- -4% _array 2621427/s 110% 74% 55% 4% --
Have a nice evening.

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.
