No, that's the problem. Everything seems to be OK...however, if you load Samigo on that site it takes 16 s!!! to finish.

As Freddy Mercury would say: "It's a kind of magic". :D

Thanks!!!

David

Hi David,

We have not seen this issue with 2.8.x.  Do you have a report on the offending slow query?

        Hi all,

        We have just migrated from 2.6.0 to 2.8.0 and are experiencing performance problems with Samigo. Here are my tests:
- I have checked if migration scripts have left some index invalid o unusable and everything is OK.
- I have checked if I miss an index creating in migration scripts and everything is OK.
- I have check if Oracle has statistics done...and everything is OK.

         The most important issue is that Samigo main page spends 16s!!!! to load 13 quizzes.

         Any idea?

          Thank you very much in advance.

          Cheers,
                David
