Summary19739: Data loss caused by excessive session size
Description

When there are many questions in the survey, the information about the questions and options is stored in the session, which leads to an excessively large session file. I have encountered a session file that is 500MB, causing occasional issues with session accessibility. This can result in data loss or persistent validation failures. I later modified the memory_limit in php.ini to 2048M, but if the number of concurrent users exceeds 5, session accessibility issues may still occur.

This raises a question: why is the question information stored in the session? Why not store it in the cache instead, so that all users share one copy of this common information rather than each having their own? Will there be any optimizations in this regard in the future?
