Download ten files in parallel from localhost using HTTP/1 over HTTPS, 10 times each - with #curl. Each file is 100MB. Limit the download speed to 5000KB/sec.
How much CPU is "good" to spend on this on a modern intel arch?
Perhaps a median of 2.73% of an i7-13700K core is okay?

(the tests run on my local machine, at that single 3.8 spike I probably did something else on the host)
@bagder does KB mean KiB in this context and M a power of 10?
I was surprised at first why it'd transfer 5.12M when you asked for 5000K, but it works out exactly if assuming a mix of units.
Would be good to be consistent, either always use K and M to mean powers of 2, or powers of 10. But avoid mixing a K that is a power of 2 with an M that is a power of 10....
I bet you then ask yourself: when you limit the speed like that, how fast does it actually transfer all those files? How accurate is it?
Answer: the span is +-1385 bytes/second, 0.03% of the mean value. Pretty darn accurate.
The graph is slightly amusing as well as the two decimals used on the Y axis are not detailed enough...
