Once survey cache has been built, loading public facing portion with newtest is quick -- but first time when cache is built, it is quite slow.
 

There are no cache for Expression in public survey, only $_SESSION are used .

Maybe twig caching ? And assets construction ?

same situation with only 15 questions. Simple new survey are saved while surveys with JS are hanging

@batpurev : pleasde don't think it the same situation without a complete control.
Thousand of people don't have issue with 15 question.

You already have your own topic and it's totally unrelated.
Your issue is related to 4.X version sure at 99.99%

I would like to provide an update -- if you comment out lines 796, 797, and 987, conditions on the questions aren't recalculated -- that is expected.

However, what I have also noticed is that the conditions are then removed for all questions. And running the Survey Logic File doesn't restore them.

I had to uncomment the lines just before the survey went live, open a question, save the question, and then all my conditions were reapplied.

Arg,

Sorry for that (i never use conditin).

really strange it was deleted …
