Dear forum-members and limesurvey-team,

we have a problem with the following question-type

* Array (Texts) and
** show totals row&columns
** show grand total

The rendering of such a question takes several seconds in lime-survey 3.X whereas the same question loads almost instantly in lime-survey 2.x. My guess is, that something has changed in the way the rendering is processed (in qanda_helper.php ?). I would appreciate if anyone had a hint or solution.

We tested it with all versions of limesurvey up to the current. It is also reproducible in the Online Demo-version of limesurey. Steps to reproduce:
* create a question as Array (Texts)
* add e.g. 3 columns (X-Scale) an 15 rows (Y-Scale)
* In Question-Settings "Other"
** set "show totals for: Row&columns" and "Show grand total"
** set "only numbers"

Thank you in advance

Axel

I can not compare with 2.73, but when checking don't see real difference between 2.6lts and 3.X
on a 2.6lts
on a 3.X without ajax mode

Same (old) server for the 2

Loading:




But right , seems performance is better when updating for 2.6 than 3.X

Did you try without ajax mode ? I always diable ajax mode (and use a theme without ajax mode).

... thanks !

ajax on/off in template doesn't seem to make a difference. i tested both links (on mac os)


* demonstration.sondages.pro/135149
** safari: about 2 sec.
** firefox: about 2 sec.

* Demo.sondages.pro/135149
** safari: about 33 sec. !
** firefox: about 7 sec.

in which browser did you test? can you reproduce the above times on firefox/safari?

best regards

axel

On firefox … don't have such difference … I check with reload current page…
Maybe some difference due to server too …

But right : if you can report (with your own server please) it can be great.

PS : i don't have a Safari box : since safari is not Free

How about uploading to something like Dropbox and send the link here? No one really wants videos via email.

This issue is not server related. It's not network related. It's browser related.
It took 32.34 s in Chrome Version 73.0.3683.103 (Official Build) (32-bit)

The long delay is mostly caused by a lot of forced reflows.



You might find delays in array filtering / ranking filtering too.

Like i say : for reporting an issue

1. Use your own server (or the your limesurvey GMBH account server)
2. Use an included theme (the default or vanilla)
3. If you can use a video recorder : obsproject.com/ for example BUT developper tool can be sufficient
4. If you can use a 2.73 version
5. Make a survey without grandtotal and same screenshot or screenrecorder

But most important (even if you can do none of the previous part) : www.limesurvey.org/community/bug-tracker

Why all the videos and own server, generic theme requirements? It's a JavaScript issue (recalculating style, reapplying style, CPU till 100%). Or the survey file itself contains something.

I can reproduce that issue (testsurvey via Demo.sondages.pro/135149 ) in
Firefox and Chrome (both Windows 7 64bit) as well.





LimeSurvey will need to start pushing updates via different tiers. The take it or leave it approach will render installations useless for productive work. And debugging bugs become more difficult, because so many commits are released at once.

1. my Demo website is on a old server (more than 11 years of services)
2. my Demo link didn't use a core template (myu template have a lot of JS too , can disable but …)

Then LimeSurvey GMBH can always say it's my server or my template … and don't fix the issue.

I think the best way is to use LimeSurvey GMBH server, but here we need to have a «it's better before» …
You can use my 2.6lts for it's better before, but for 3.X issue : use a clean setup on a clean server, OR limesurvey GMBH server (not Demo because Demo is wiped ech night).

You can use shnoulle.limequery.com/135149?newtest=Y&lang=en for reporting.

PS : strangely : i don't have such big issue on Firefox/Linux or Chromium/Linux : linux POWA \o/
