Our database is currently facing an issue where the CPU usage reaches almost 100% every day during the daily operations. For your information, we have hosted the Odoo apps on Amazon Web Services and are using version 14 of Odoo.

We analyzed using performance insight AWS where there are some slow queries in odoo as the below
"SELECT "account_move".id FROM "account_move" WHERE ("account_move"."reversed_entry_id" in (?)) ORDER BY "account_move"."date" DESC,"account_move"."name" DESC,"account_move"."id" DESC"

As we know, the above query is default in Odoo and wasn't customized by our developer. My question is:
1. Have your customers ever had the same experience as us?
2. can you give me some advice so that this issue does not happen again in the future?
3. Could you please provide me with some advice on how to optimize the performance of an Odoo database, based on your experience?
