This happens with both Armbian Bookworm and Armbian Trixie OS
I dont understand why.
Did you check with htop what processes are eating the cpu capacity ? That might give an indication.
Maybe the orangepi / armbian gcc is configured differently, or maybe there’s something going astray with the starch CPU detection etc. The upstream Raspbian gcc armhf package is not configured the same as upstream Debian..
Comparing the output of dump1090-fa --version (look at “detected runtime CPU features” and “selected DSP implementations”) would be a start. comparing gcc -v may also be useful.
Thank you @obj for providing insight.

nothing obvious there, other than that’s a newer gcc than what we used to build the bookworm packages:

Maybe armbian feeds in different optimization flags to the package build, or something. You’d have to build under the two environments and take a close look at the build logging.
The armbian os bookworm & trixie for OrangePiPC are done by Armbian “community” developers and may be they have configured gcc differently.
On the other hand the Armbian for Raspberry Pi are done by armbian’s “mainstream” developers, and dump1090-fa built on this distro do NOT give any issue. I have written to microSD card, the Armbian forky for RPi model 4, and both dump1090-fa and piaware work perfectly OK.
Following two packages I built on RPi Model 4 using Flightaware source-code both work normally
