bug#25045: [Website] Packages page takes too long to load

[Luis Felipe López Acevedo]

Steps to reproduce
==================

1. Open a Web browser
2. Go to https://www.gnu.org/software/guix/packages/
3. Download the page, and check its size


Unexpected behavior
===================

* The page takes almost 60 seconds to load when visited for the first
  time, and about 30 seconds when is cached.
* The page is 9.9 MiB in size.
* The browser becomes unresponsive while the page is loading.


Expected behavior
=================

The page loads so fast that nobody will file a bug.


System information
==================

I tested the page with the following hardware and software:

Desktop computer
    OS: Debian 8.6
    PROCESSOR: AMD Ahtlon X2 245
    RAM: 1.9 GiB
