S p a m m y s y s C a l l s in strace dumps
Yeah, excellent description of why the volume is so high, and when you're tracing a multithreaded one there's the additional noise from the way they're interleaved.
Besides filtering, I forgot to mention that some kind of aggregation/summary. strace flags are useful; even better to write a little program with eBPF (on Linux) or DTrace (on macOS/BSD/Solaris). I like being able to do stuff like this: https://github.com/scottlamb/retina/issues/5#issue-933945792
- Managing and using ONVIF IP cameras with Linux

Async cancellation: a case study of pub-sub in mini-redis
I suspected exactly that in this issue in one of my libraries, but when I actually looked with strace, I didn't see many syscalls returning EWOULDBLOCK. So then after that measurement, my new theory was that e.g. tokio::net::{Udp,Tcp}Socket would skip actually issuing the syscall if the mio layer hasn't returned availability since the last poll. Not true? Maybe I need to run my experiment again...
