I know this is really old, but honestly I have a hard time navigating and making sense of jira. I have a site on 7.3.4 and am experiencing this issue. I won't go into details as to why I need this to work but it is to keep things in order using a bootstrap responsive skin. I need content to show:

abcd
efgh

on desktop and

a
b
c
d
e
f
g
h

on mobile. If I do this using less HTML modules, I end up getting a then e when in mobile view. This particular site is running on a very fast server, xeon processors, 32 gb ram. I have no issues with speed with 200-300 simultaneous forum users, 10k-15k visitors per day etc. Its only in edit mode on pages with 15+ html modules.

Has anything ever been done about this? I'm assuming no because I see this exact behavior on 7.3.4. Same page in view mode is smoking fast. Switch to edit mode and its slow as molasses. I basically have 15 html modules, each with a 4k graphic inside centered. The first thing I do is add the modules to the page and after about 10-11 modules this task becomes very tedious waiting.

Like I said I hate to resurrect a year old thread but this describes my situation exactly. Just curious to hear any developments.

Thanks!!

Thanks Cathal and thanks for deleting my duplicate. I must have hit submit twice.

So I did what you said, I'm not great at doing these things. But I did take a look at timeline in chrome (mac). I am running DNN 7.3.4 (Build 45) so I'm well past where this was fixed. The issue doesn't appear to be with the html modules. The items that are taking the longest to load are from dnncontrols.dnntoolbar.js Like I said I really have no idea what I'm looking at here but that is what loads last in timeline and shows is loading very slow.

I do frequent work on this site and have always had issues with cache so i'm clearing cache and refreshing the page often. I tested it both before and after clearing browser cache and I don't see a change.

I do find it strange that the ONLY pages this happens on are the pages with many html modules. I load a page like host > settings right next to it, with stay in edit mode checked and it loads in no time at all.

I do notice something else that may be the problem. I've never been able to duplicate this. I have about 50 DNN sites and this site is the ONLY one that I can do this on.

I have somehow enabled a quick edit function in html. I have no idea where it came from or when I realized I could do it, but on an html module using a container like transparent no title, I have a pencil icon that if I click on I can easily edit html content inside an html module without having to go to edit content and edit inside the HTML editor (that was really wordy but I think it makes sense). I really do like this function especially when making quick html edits. But I honestly believe that this may be the reason for the slowness. I don't see this feature on other DNN sites and could live without it if it were the culprit.

Do you have any idea what I'm talking about? If so any idea how to disable it so I can test and see if the problem goes away when its disabled? It may be something the original designer turned on way back in early V5 days when the site was created. I have looked and looked everywhere to see where this is, I've searched for it on google and looked everywhere and I can't find what it's called or how to edit it.

Additionally, on an HTML module with a container and a title, this function only allows me to edit the module title and not content. The same exact function on a transparent no-title container allows me to edit html content in a very limited html editor like function. I click save, the page doesn't refresh and the new content is saved. All without going into html editor.

Any ideas of have I completely confused the situation? It makes sense in my little brain :-)

Thank you for answering!

Hey Cathal, if I need to move this somewhere else I'll gladly do so. I hate to hijack someone else's thread.

Thank you for clarifying the inline editor. I had no clue what to call it so I have never been able to find what it was called or how I got it turned on. At the very least I learned that :-)

I turned off the inline editor and I still see the same issue. I see it around 12 HTML modules. What I find strange is that the page loads slowly and if I catch it quick enough I can see that all of the html modules are rendered before the lag, what appears to take the most time are the actual dotted borders around the modules, and module related icons.

So I did a test to see what I could find out. I created a page with about 20 html modules on it using gravity home skin and gravity no-title container. The first 5-10 html module added no problem at all no lag whatsoever. After about 10 each one from there on out got slower and slower at page refresh. I added 10 more. Each one progressively got worse. After adding I switched over to my site's skin and container and really saw not much difference. Still relatively slow.

So I'm not sure where to go from here. While trying to track this down, i have learned another way to accomplish what I want to without needing so many modules but for argument's sake and to keep my site's performance at it's peak, do you have any other suggestions as to what I can look at and try to find out what's going on?

Thanks for your time
