change php version

Question

after changing php version from 5.6 to 7.0, the site has become very slow, in the log file began a long process it is to submit a request to the database from the script no identified problems (if the clean install script to 7.0 everything works well and no long processes when accessing the database) 

May be something written in the database (maybe cookies or something) which does not allow it to correctly upgrade to the new version of php 

hope for helps

Which version of Q2A you are using? It should make site faster after upgrade to 7.0, may be some other issue. What is version of mysql you are using?

the problem with the long load and query the database data is only for registered users, anonimnie users do not create a lengthy process, and quick to send questions or answer
previously, all work, but when switching to another version of php, to start this problem
the website and scripts are working fine but when upload the old database to start problems with the increased load
problem: ask question, answer question, vote (CPU to use 2 cores for one process mysql)
no problem: edit the question
this is only for registered users
anonymous users do not have these problems
