Large Json Files

Hey guys,

I created an API that adds records to a table from a json record list. Everything goes very well when I send up to 1000 records in json.

When I send larger files, with 5,000 records for example, the API response time gets huge, it returns a runtime error message and, when I go to see the database, it saves 3 times the number of records that had been sent in json. Always 3 times the value.

How do I resolve this? I need to send files with 15K to 30K records.
