Here's an example from the Mojolicious Cookbook:

use Mojo::UserAgent;
use Mojo::IOLoop;

# Parallel non-blocking requests
my $ua = Mojo::UserAgent->new;

$ua->get('http://metacpan.org/search?q=mojo' => sub {
  my ($ua, $mojo) = @_;
  ...
});

$ua->get('http://metacpan.org/search?q=mango' => sub {
  my ($ua, $mango) = @_;
  ...
});

# Start event loop if necessary
Mojo::IOLoop->start unless Mojo::IOLoop->is_running;

So in this example there are two GET requests sent, and callbacks execute once the requests are fulfilled. The event loop is implemented by Mojolicious's standalone event loop, but if you have EV installed on your system, internally that will be used automatically, for improved performance.

Non-blocking concurrency seems to be a strong focus in Mojolicious's ongoing development. As a UserAgent, it's probably hard to find a solution that has better non-blocking IO support from its developers.
