SRE graph scrying test:

I'm backing up a bunch of files to S3, there's moments where the throughput goes down and moments where it goes up.

Assuming no network activity in a way that matters, why would the throughput number be going up and down like this?

@cadey The numbers going down mean lots of little small files. Going up means big long transfers.

@glitchf Correct!

@cadey @glitchf some of the better s3 tooling (eg rclone) have ways to mitigate this via more concurrency
