Hey everybody,

I have written an application for some networking tasks that runs in the user space of my Yocto-Linux.
I noticed a dip in performance running the --release version.
Afterwards, I’ve tried different opt-levels and explicitly setting target-cpu, but without improvement.

I realise it is probably a "me problem", since i have a hard time finding any sources talking about problems with the optimization. If you got any pointer on how to pinpoint the issue, I would greatly appreciate the help. Thanks in advance!

Context:

• Target: Rock Pi E (Arm Cortex‑A53 64‑bit)
• Build system: Yocto, using a sourced SDK
• Cross-compiling Rust (not building natively on the device)
