LWP::Simple is not faster than LWP::UserAgent since it uses LWP::UserAgent. It's just a simpler interface.
is LWP::Simple faster than the full LWP?

I'm sometimes use the LWP::Simple Perl module, which I understand is a reduced version of the full LWP module. I use it blindly because somebody suggested i use it a while back. What is the benefit of using it over the full package, is it faster and is it easier to use?

Questions of the "is A faster than B" sort, should always get the same answer: try it! In your environment, with the kind of data you generally use, etc. Here's a short script to get you started:
use strict;
use warnings;
use Benchmark qw/ cmpthese /;
use LWP::UserAgent;
use LWP::Simple;
my $url = 'http://localhost/';
my $ua = sub {
my $ua = LWP::UserAgent->new;
my $res = $ua->get( $url );
if ( $res->is_success ) {
my $content = $res->decoded_content;
}
};
my $simple = sub {
my $content = get( $url );
};
cmpthese( -60, {
'LWP::UserAgent' => $ua,
'LWP::Simple' => $simple,
});
On my system, where http://localhost/
will return a tiny index page, LWP::Simple
is actually slightly slower:
Rate LWP::Simple LWP::UserAgent
LWP::Simple 401/s -- -3%
LWP::UserAgent 414/s 3% --
But it's hard to tell what will haven, when the URL gives you a DVD image, e.g.
