Question

I’m running Dancer and found it slow — pages took a long time to render.

This is the example code from Dancer::Introduction:

#!/usr/bin/perl
# make this script a webapp
use Dancer;
# declare routes/actions
get '/' => sub {
    "Hello World";
};
get '/hello/:name' => sub {
    "Hello ".param('name');
};
# run the webserver
Dancer->dance;

It takes my browser 10 seconds to get&render the response( using firebug in firefox ).

And Dancer message:

[20734]  core @0.000228> request: GET / from 192.168.1.101 in /usr/lib/perl5/site_perl/5.8.8/Dancer/Handler.pm l. 57

[20734]  core @0.000873> [hit #45]response: 200 in /usr/lib/perl5/site_perl/5.8.8/Dancer/Handler.pm l. 175

Why is Dancer so slow? Did I miss something?

Is the computer connected to internet? I got the same problem when testing from a computer not connected to internet; fixed it by deleting
