I have a VPS 2GB RAM 2 CPU. On a local VM with 1GB RAM and 1 CORE the following script takes just under 2 seconds to run:
!/usr/bin/perl
use strict;
use warnings;
use Mojo::DOM;
use Mojo::UserAgent;
use Data::Printer;
my $ua = Mojo::UserAgent->new;
my $url = 'http://www.testURL.com';
my $page = $ua->get( $url )
->res
->dom;
my $dom = Mojo::DOM->new( $page );
for my $deal ( $dom->find('p.title > a.title')->each ){
ProcessLink( $deal->attr('href'), $deal->text );
}
sub ProcessLink{
warn "process link\n";
my ( $linkURL, $linkText ) = @_;
print "Link: $linkURL | Title: $linkText";
}
The exact same code on the VPS takes 1m 57s to run. Networking from this VPS is fine, using top I see the CPU is maxed out, when Mojo::DOM-new is called. Is there anything I can do the make the run faster? A wget of the page from the shell is instant (VPS in a data center)
