Hey Suraj,

I am facing the same issue in both SugarCRM versions 13.x and 14.x.

Hi Dhirendra,
Are you using upgraded version of Sugarcrm?

Hey Liam Hastings,

We've already tried the same, and with MySQL 5.7, it works faster. Yes, if I remove the following:

ORDER BY leads_cstm.last_call_date_c DESC, leads_cstm.id_c DESC

it performs better, I know this part, but we need this. However, as you know, we need this for the UI list view in SugarCRM.

I reviewed the query with EXPLAIN, and it is not using the same index. Unfortunately, we cannot force the use of that specific index.

DHIRENDRA KUMAR You might find you just need to add a custom index to the leads_cstm.last_call_date_c field. I suspect if you run the query without the order by it is probably fast. Running an EXPLAIN on that query will highlight if it is failing to use an indexes
