I noticed that there is a considerable (5x) performance penalty when upgrading my app from InfluxDB 1.8 to 2.0. I'm using ILP and the only change I made on the ingress side was switching from /write to /api/v2/write, adding the auth token and org and bucket query parameters. I am writing 25,000 data points per second in bursts of 100 data points using 10 connections in parallel. My laptop runs at ~18% with 1.8 and ~94% with 2.0.
Is this an expected behavior? Maybe some default database performance settings changed?
