This saved my raspberry.
Thanks!
I have a Pi 4, 1gb Ram, and it got constantly slugish, especially with InfluxDB installed.
Changed to SSD; changed different USB Sata adapters, but still the same.
Then i found this! Now my raspberry runs with no problems, only logs take some minutes to load. InfluxDB is still not installed, will use it it some weeks without changing much for testing.
This should be mentioned in the Docs, e.g. here:
