Notes from testing (using KTD)
==============================

I would say this makes a really good difference - apart from the System
information tab, every other tab feels faster to load.

I'm assuming for the system information tab that there is a lot to check, and
this will depend on the Koha instance configuration.

Before the patch
~~~~~~~~~~~~~~~~

- Initial: 19 requests 1.23 MB / 59.46 kB transferred Finish: 3.77 s
DOMContentLoaded: 3.75 s load: 3.75 s
- Reload (go somewhere else, such as the home page, then go back to the Abut
Koha page): 18 requests 875.75 kB / 59.45 kB transferred Finish: 1.28 s
DOMContentLoaded: 1.26 s load: 1.27 s
- Refresh the page (Shift + Refresh button): 30 requests 1.78 MB / 389.59 kB
transferred Finish: 1.38 s DOMContentLoaded: 1.37 s load: 1.39 s

Note: With a refresh, a recurring error is (Bug 34973): downloadable font:
Glyph bbox was incorrect (glyph ids 1 2 3 .......) (font-family: "Font Awesome
6 Free" style:normal weight:900 stretch:100 src index:0) source:
http://127.0.0.1:8081/intranet-tmpl/lib/fontawesome/webfonts/fa-solid-900.woff2
