Thanks @serg38,
You answer helped a lot.
I just do not fully understand the deletion of the indexes, for instance,
you delete index “id” and “id_2” from table “domain_router”. Does that mean
that the table has three (3) indexes?

> h2. General DB Optimization
> In some production environments there were being experimented delays in most
> of the jobs. A search for DB optimization was taken and some deficiencies
> were discovered, we can group them in 4 groups:
> * Incorrect PRIMARY key
> * Duplicate PRIMARY KEY
> * Missing indexes (Add indexes to avoid full table scans)
> * Some views query (Change view to improve account retrieval speed)
