Online Slowness - How to Speed Up a Mammoth Online Merged HTML5 Help System?

Hello all,

Product and Project details:

  • RH 2017 (13.0.2.334)
  • Merged help system of about 20 help projects (~467 MB total when generated)
  • HTML5 output

We are experiencing some slow speeds when loading in the merged help site from our online webserver. One user who has 20 Mbps download speeds, it took him about 11-12 seconds to load the site, and about 19 seconds before they get search results. (I'm sending out a survey in our company to get broader results, but I've seen slow loading and search speeds results from my computer as well and I have about 80 Mbps download speeds.)

For example, when I run the site through google's Page Insights (Desktop not Mobile-- Mobile is even slower), I get this:

Look at that "Time to Interactive" stat. Yikes! Anyone else see something similar on your large merged HTML5 sites?

I personally don't know what I can do on my end to optimize to increase speeds. This all seems to stem from how RH merges everything together with this particular layout.

Thoughts?

    I seem to remember reading years ago that it's to do with the merge code combined with the number of projects merged (getting slower with each project added) and I don't think there's really anything you can do about it beyond raising it with Adobe.

    If you have google analytics enabled, you could check the Site Speed > Speed Suggestions page, to see what suggestions are offered. I can't help with that though, as I only just discovered it exists, and have to figure out why I don't have any data.

    Can you share the output with me? I would like to upload it to my server and see if it is the same there. It would only be there for long enough to compare with your site and then it would be removed, a matter of minutes.

    If you can share, you know how to send it. Also send a link to your server so that I can compare.

    Hi Peter. Certainly. I sent you a private message with the links. Thanks again for your help.

    Amebr, thanks also for your comment. I may look into Google Analytics. (We do have Application Insights enabled on our webserver which may help us track down some info as well, but I suspect this is indeed a RH issue and how they merge the child helps together and present that data.)
