Ok, i give you more info on images, for try to help me figure out where is the problem.
LS info:
 

Php info:
 

Also, i installed a local LS5 on XAMPP, to look how activate and see the errors on Limesurvey, i do it first on a local installation because i dont have much experience with this and i dont want to mess up with my main installation, i activate de debug mode on config-defaults.php changing $config = 0; to $config = 1;

I restart the server (i know this is probably not neccesary) but i dont see any difference on LS, once i activate the debug mode, where can i see the errors if theres any error?

And the slowness is weird, works slow when you click "list surveys" or when you click on a survey, but when you have selected a question and push on "modify" the question works instantly, some things takes between 5-10 seconds to load, and others is almost instantly, like they should work.

I think too, to install a new one fresh version, but i have active surveys right now and think on export and import all the surveys to the new installation makes me sweat, and i have LS on a subdomain that i want to keep being the same direcion, so, if we can fix this i prefer it instead of make a new installation, but thanks for the idea.

i activate de debug mode on config-defaults.php changing $config = 0; to $config = 1;

That change should be made in config.php, never modify config-defaults.php.

Ive been searching for my problem and i found this:

forums.limesurvey.org/index.php/forum/in...slow-loading?start=0

The same thing is happening to me, and on that case seems to be fixed checking out "ComfortUpdateChecker" and "UpdateCheck" on the plugin section.

I deactivate it on my LS but, the popup saying that i have a new update keeps showing up, ¿is that normal if i deactivate the plugin?

And another thing i notice, i installed a new LS on my local machine to do tests, and on my LS on local machine, with the same version of LS 5.6.36 i have the "Update check" on plugins, thing that i dont have on my main LS wich i update via ComfortUpdate, ¿can this be the cause of my problems?

And i see i can delete "ComfortUpdateChecher" from plugins, is there any risk if i do it?

Thanks for the help.

More info, and sorry for the spam, ive been looking on the files of Limesurvey to see if the UpdateCheck plugin is in there and i found this on Aapplication/core/plugins, the plugin is in there, but theres no appear on Limesurvey plugin page to deactivate it.

It is safe to delete or copy on another place the ComfortUpdateChecker and UpdateCheck to make sure that is not that plugins wich is causing me the slowness on Limesurvey?

Thanks for the help.

Don't delete it, simply disable it.

I already do that, for that reason i ask if i can delete it, because ComfortUpdateChecker is disabled and UpdateCheck is not on plugin listo to deactivate it, but i see it on the folder.

And LS keeps slow on admin side with ComfortUpdateChecker disabled, i wonder if i delete that folders i make sure that is not ComfortUpdateChecker or UpdateCheck is behind making bad things.

Thanks for the help.

If the plugins are disabled, removing the folders will no affect anything.

Ok, i dont know why, but my last change was to reactivate ComfortUpdateChecker plugin and deactivate it again, after that i have a lot of work the next days until the last week, and when i go in back to Limesurvey, seems like is all going good again.

When LS runs slow takes me 20-30 seconds to save a change on the survey options, now take 3-4 seconds, and the rest of the admin interfaces responds almost instantly.

It looks like the problem is solved, but i cant make sure that was the problem, if the problem comes back i let you know.

Thanks to all the people for the help they gave me.

Hello,

We are having exactly the same problem, with version 5.6.26 installed on a quality hosting provider with a dedicated server.

We have observed the problem with large surveys, as in the same installation there are small surveys where the slowness problem in the survey configuration area does not exist.

We are talking about a survey with 650 questions organized in 30 groups. These questions are conditional and only 10% are presented to the user depending on an attribute.

Changing any element of the survey configuration area (administrator name, survey name, notification email, whatever) takes more than 3 minutes each time the "Save" button is clicked.

Splitting the survey into smaller ones is not an option. We make more than 400 copies of that survey every year and each of them has different users and different activation times.

However, there is no problem with the Survey Menu options or with editing the questions. In those cases, the saving times are normal. The response time for the survey users is also normal. There is no performance problem.

Any thoughts? the installation works fine with small surveys, so it is unlikely that the problem is due to software or server installation issues.

thanks in advance.

Check what happens when using LimeSurvey 5.6.56.
If only one survey and it's copies are having this issue I would recommend to create another copy and delete parts of the survey and deactive certain functions to see if you can find a change in speed. Or create a dummy survey and replace all the survey text with generic text that would allow you to share a LSS export here on the forum to allow other to try to reproduce the issue.

Deleting parts of the survey would mean having a smaller survey, so the problem would disappear or become smaller.

The problem does not only occur with a survey. It is proportional to the size of the survey: the more questions the survey has, the longer the survey setup area operations take.

I have pointed out the most serious case, with 650 questions (and 2 languages) and three minutes to save a modification in a field. But we have earlier versions with 250 or 300 questions where the time to save is 1 or 2 minutes.

thanks for your answer

If you are 100% sure about this, fine. But I find Jelo's approach valid. There might be issues with certain questions, certain equations, etc.

This might be purely survey size related, but it might actually not.
Help us to help you!
  • Provide your LS version and where it is installed (own server, uni/employer, SaaS hosting, etc.).
  • Always provide a LSS file (not LSQ or LSG).
