I don't know if your webshop is fairly large.Otherwise I would like to ask you to create a subdomain called : dev.swimrunland.fr and copy the entire site under this domain. The also copy the database.
Then we need to start disabling modules one by one and check the performance impact. Possible there is a module that has a negative impact.
Before you do all this, please check the server logs for any remarks. Possibly you see something like err_xxxxxx timeout blabla etc etc. So you know where the issue might be. However this is an option.
If all of this fails, we need to run this website locally and run XDebug. The make a performance profile and use cachegrind to find the functionality that consumes the most and possibly eliminate this.
Thank you dear Alex,
Iwill try to do this and let you know.
For the server logs, i don't know where to find it i'm not that expert:/, would you mind show me where i can find it?
