Django Serializers running slow to convert JSON

I have 5 different Foreign Key values in 1 model. There are 1800 records in total.

Using AJAX it is necessary to convert the data to JSON format. I can do this with the Serializers library. I use use_natural_foreign_keys = True for Foreign Key values to return string values.

use_natural_foreign_keys = True

  • When i use it; 15 seconds of query
  • When I am not using it; 0.5 second

But I have to use it. Otherwise, I cannot get Foreing Key values when converted to JSON format.

I leave the query here. How can I make queries faster? Thanks in advance.

     jsons=serializers.serialize('json',result, use_natural_foreign_keys=True)
