algorithm::diff::xs
Algorithm::Diff::XS(3pm) User Contributed Perl Documentation Algorithm::Diff::XS(3pm)
NAME
Algorithm::Diff::XS - Algorithm::Diff with XS core loop
SYNOPSIS
# Drop-in replacement to Algorithm::Diff, but "compact_diff"
# and C<LCSidx> will run much faster for large data sets.
use Algorithm::Diff::XS qw( compact_diff LCSidx );
DESCRIPTION
This module is a simple re-packaging of Joe Schaefer's excellent but not very well-known Algorithm::LCS with a drop-in interface that
simply re-uses the installed version of the Algorithm::Diff module.
Note that only the "LCSidx" function is optimized in XS at the moment, which means only "compact_diff" will get significantly faster for
large data sets, while "diff" and "sdiff" will run in identical speed as "Algorithm::Diff".
BENCHMARK
Rate Algorithm::Diff Algorithm::Diff::XS
Algorithm::Diff 14.7/s -- -98%
Algorithm::Diff::XS 806/s 5402% --
The benchmarking script is as below:
my @data = ([qw/a b d/ x 50], [qw/b a d c/ x 50]);
cmpthese( 500, {
'Algorithm::Diff' => sub {
Algorithm::Diff::compact_diff(@data)
},
'Algorithm::Diff::XS' => sub {
Algorithm::Diff::XS::compact_diff(@data)
},
});
