We have 2 dedicated servers. One server contains a VM in which nginx is running.
Another server contains a VM in which a database mysql is running.
We have configured nginx and connected to mysql. The setup is fine and working correctly. However what we have noticed an issue with performance of page loading.
There is no issue with the application code, because same code and database is running on another server already. Its a live site and we had to migrate to our servers. And on live site, we are not facing this issue.
So there is no need of doing any application level optimizations.
However what is required to be done is debug the setup and check why the page loading is taking time whenever any node save happens and fix it.
