Summary13966: Slow admin interface, js runtime violations and error accessing assets

Since the update from 2.73 to 3.x, our users have been complaining about slowness on the admin interface and also while taking surveys (sometimes timing out on them in the middle of taking some surveys). I'll concentrate on the admin interface part for this ticket, but I suspect the slowness while taking the surveys may be due to the same cause(s).

When clicking Edit on a question, the editing page takes no less than 7 seconds to load, and when it is rendered, the rich-text fields (Question and Help) don't show up until at least 15 seconds later. This didn't happened on version 2.73 when times to render were always under 5 seconds, for the same Limesurvey installation.

I see a lot of javascript runtime violation warning messages logged on the Developer Tools console in the browser, ending with an error trying to get "balloonpanel.css" from /tmp/assets

I have attached the console log file.

If additional information is needed, please let me know.

Hi again!

I updated to the most recent stable version (3.14.5+180815) and the problem persists. I made sure to clear the assets and browser caches as well. Browser console log attached.

OK I have tested this, on a recent chrome canary install. It seems that there is a problem with ckeditor.
The ckeditor scripts are not singletons, so they replicate all over the page.
We will have to do some serious refactoring here.

Any update about this issue?

This is still an problem in the most recent stable version (3.16.0+190225). Taking a long time for the Edit page to load, with an error logged in the browser console about not being able to get "balloonpanel.css" from /tmp/assets

In 3.17.1+190408 I still see the error with the missing balloonpanel.css:

In tmp/assets the skin bootstrapck is missing but in assets/packages/ckeditor/skins it exists.

we're working hard on LS4, and in LS4 the admin panel will be new. That's why we're not that much into LS3 back-end optimizations right now. I will still ping markus about the balloon panel problem.
Meanwhile, I suggest you update to latest version via comfortUpdate, and you use a more powerful server and computer.
We've noticed here that LS being installed locally on cheap machine using Windows is extremely slow. If you're using windows as a server, you must use a powerful machine.
On a linux machine, it runs smoothly even on cheap hardware.

I understand your priorities,
Just wanted to add info to the "balloonpanel" issue: our limesurvey install (which at the moment we are not allowed to update) is on a linux virtual machine and indeed it's not slow at all. Anyway the error record is always present. So i guess the two issues are not related, or not?

thank you for that feed back. No they're not related. I'll tell Markus to fix the balloon one.
