alt Hacker NewsReally stupid question from someone who doesnt know much about io_uring. Wouldn't doing all this i/o async make the latency measurements less accurate? How do you know when the i/o starts if you are submitting it async in batches of 2048?

Its not a stupid question.
Normally when I have run latency calculations in the past I run them from the perspective of the caller, not the server.
In most cases this is over the network, a named pipe or sock file.
I guess it should be possible to run multiple runtimes inside a program that run independently.
