Hi haukex,
You might want to also try using a file handle opened on a reference to your string:
filehandle => sub {
my @lines;
open my $str_fh, "<", \$str or die "cannot open fh $!";
while (<$str_fh>) {
chomp;
s/o/i/g;
push @lines, $_;
}
},
This appears to be faster than your other subs, including the one with split (note that I had to change the count value for the result to be meaningful):
$ perl bench_split.pl
s/iter regex index split filehandle
regex 3.44 -- -9% -36% -48%
index 3.13 10% -- -29% -43%
split 2.21 56% 42% -- -19%
filehandle 1.78 93% 76% 24% --

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).
