Write Delays in measurements

We have a django rest framework running with Influxdb as DB.
Sometimes, when request is posted to the server, InfluxDB is taking more than 10 secs to insert records in one of my measurement (Records are received at the same time, but got inserted after 13 secs as seen in below log lines).

**2022-02-10 09:11:34,268** : INFO: Record [{'measurement': '', 'fields':{'timestamp': '2022-02-10 09:11:34', 'authorized': False, 'enabled': True}, 'tags': {'agentName': ''}}] inserted successfully to default.agentChangeInfo!!

**2022-02-10 09:11:47,900** : INFO: Record [{'measurement': '', 'fields':{'timestamp': '2022-02-10 09:11:34', 'authorized': True, 'enabled': True, 'splitState': False, 'stateChange': 'active'}

No files, tests, versions, or entry points are named. Start by tracing the POST request through its InfluxDB write call and correlating the logged timestamps with client, server, and database behavior; done means identifying a reproducible cause for the 13-second delay or documenting why it cannot yet be isolated.
