Make Oxygen webhelp load faster

[tomjohnson1492]

Although the webhelp files are simple static files, they sometimes take a while to load in the browser. For example, go to http://tools.pingdom.com/ and load this file: http://idratherbewriting.com/ditaqrg/.

Here's a report of the loading time by resource: http://www.screencast.com/t/0DubzMjFAjd2.

It takes about 2.5 seconds to load. For topics that have screenshots, the loading time is longer.

Static files should load within 1 second, especially if they're just text. Oxygen has a ton of js scripts that are taking a long time to load.

Load time issues are even more apparent when I load actual files I produce at work from other servers (I just can't post them here), but load times are around 3 - 4 seconds.

This is becoming an issue. What JavaScript files can I get rid of here to improve the loading speed? I already minified everything. It would be great to see a list of css and js files, what they do, and how to disable them.

For example, index-1.js, index-2.js, index-3.js -- what are these doing? Do I need them? What is htmlFileList.js doing? Need it? localization.js -- am not localizing anything at the moment. jquery.ba-hashchange.min.js?

Any other tips for making Oxygen load more quickly?

We are working on the load time of the WebHelp pages. In the next version of Oxygen the load time will be improved in a very visible way for the user that loads a WebHelp page in a browser.

For example, index-1.js, index-2.js, index-3.js -- what are these doing? Do I need them? What is htmlFileList.js doing? Need it?

If you don't use the Search tab in the WebHelp pages you can remove them.

localization.js -- am not localizing anything at the moment. jquery.ba-hashchange.min.js?

These two files are required, are very small (1 KB and 2 KB) and their file length is constant with any WebHelp pages.

It's great to hear that you're working on improving the loading speed in the next version. I'm looking forward to it. Is that in v 17 or a dot release in v16?

It is version 17.0. We hope to have the speed improvements ready until the release of version 17.0 next year.

The speed issue is killing me. Sometimes it takes 3 seconds for a basic page to load. Given that there's no database query here, I can't imagine where the latency is. This issue a huge priority for me to get fixed. Thanks.

Do you mean it takes 3 seconds just to load a short WebHelp page in the browser? Did you check the speed of your Internet connection?

Is the page short but is part of a large set of WebHelp pages, which means you have a large total number of topics in the Content tree in the left-side panel of the WebHelp page?

These are possible causes of such a long delay. If they do not apply to you maybe you can send a set of sample files for reproducing the problem: a small sample DITA map and all DITA XML topics included in the map, together with the WebHelp pages generated by the DITA WebHelp transform?
