Defer loading Textpattern form
I have a site that loads map data on certain pages. The map is selected by a tab.
Example page: http://marineweather.net/coastal/boston-harbor-coastal-forecast
Everything on the page loads initially, although the map is not seen by a site visitor unless they click the map tab. The map is a cool feature, but it’s size means that 90% of a page load is loading that map. I’m seeking to make page loads snappier.
The data that creates the map is all on a Textpattern form. It includes js & css & json files. The Textpattern form is useful as there are TXP tags used that make the map unique to every page it is used on. As a result, I’d like to continue to use the form.
Is there a way to delay loading a Textpattern form? A delay of 2 seconds for example would make page loads faster, while still providing the map to those who use it well ahead of when they would likely click the map tab.

Re: Defer loading Textpattern form
I would create a separate page for the Map tab, but there are also couple other things to consider:
Source code in Boston Harbor Marine Forecast page suggests jQuery library is loaded several times:
First time:
<script type="text/javascript" src="https://code.jquery.com/jquery.min.js"></script>
Second time:
<script src="//code.jquery.com/jquery-1.11.0.min.js"></script>
Third time, perhaps:
<script>window.jQuery || document.write('<script src="https://ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js">\x3C/script>')</script>
Then there are couple fonts that are loaded one by one. They can be smushed together like this:
<link href="https://fonts.googleapis.com/css?family=Oswald:300,400|Roboto" rel="stylesheet">

Re: Defer loading Textpattern form
Your page speed is not too bad, see the Pingdom Tools report
From that there are a few areas of note, which would probably be better gains than trying to delay Textpattern loading:
- The JSON files from
mwx-13bc.kxcdn.com/jsonpoly/make up over half the page weight – can you cache those for a certain amount of time (say 5 minutes or preferably more) using a plugin like etc_cache – see how I do something similar to throttle the GitHub API for Textpattern.com here - You seem to be loading two separate versions of jQuery?
- Consolidate Google Fonts into one HTTP request roughly like so:
<link href="https://fonts.googleapis.com/css?family=Oswald:400,300|Roboto:300,400,500,700" rel="stylesheet"> - You may be able to reduce that render blocking 1s wait and load for
mwx-13bc.kxcdn.comJSON items by preloading?
