Hi, Egen.
I’ve connected to your app and tried to make simple requests to retrieve data from the tables.
Some requests perform fast, some do not. (It’s worth saying that now our servers are working without any problems).
For example you Order table is overloaded with columns – 60+ is really big amount as for object representation. In addition it has relations and you enabled “autoload” option for them, so the backend must get them too. Thus small wonder the request takes so long time (for me about 40-50 seconds!).
I’d would recommend to rewrite your code that works with persistence layer, so it gets only required fields and relations.
And secondly, change the schema table design in order to eliminate big amount of columns in it.
