As dwildesnl suggested, reversing makes it significantly faster: see benchmark below. But don't do the optimisation unless you need it!
my $data = <DATA>; use Benchmark "cmpthese"; cmpthese(10_000, { "reversed" => sub { my %hash; my $reversed_data = reverse($data); $hash{reverse($2)} = reverse($1) while $reversed_data =~ /\s*([^=]+?)\s*=\s*(\w+)/g; }, "non-reversed" => sub { my %hash; my $data = $data; $hash{$1} = $2 while $data =~ s/\s*(\w+)\s*=\s*([^=]+)$//; }, }); __DATA__ option1 = value0 value1 value2 option3 =value3 value4 option2=value5
gives results:
Rate non-reversed reversed non-reversed 1263/s -- -89% reversed 10989/s 770% --

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.
