( #3333=superdoc: print w/replies, xml ) Need Help??
Benchmarking it on my machine shows the multi line version running faster than the one liner.
use Benchmark; @array = ('elementary school', 'blah blah blah', 'stuff', 'hello', 'ya +y'); timethese(100000, { 'one line' => '&one_line', 'multi line' => '&multi_line'}); sub one_line { do {s/\s+/\t/; s/elementary/my dear Watson/g;} for @array; } sub multi_line { for ( @array ) { s/\s+/\t/; s/elementary/my dear Watson/g; } }

Output:
multi line: 5 wallclock secs ( 5.04 usr + -0.01 sys = 5.03 CPU) @ 19880.72/s (n=100000)
one line: 5 wallclock secs ( 5.72 usr + 0.00 sys = 5.72 CPU) @ 17482.52/s (n=100000)

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 or How to display code and escape characters are good places to start.
