Mode a/c affecting ADSB/Mode-S performance?

Hi!

In the early days when looking into mode a/c with dump1090-mutability (early ~1.14 and such) there where some issues with performance for mode-S/ADSB when a/c where enabled.

Reading the changelog for dump1090-fa there seems to have been some work to mode a/c decoding since then.

Is there any downsides (performance-wise) enabling mode a/c with dump1090-fa version 4.0 on a running installation today?

If your RPi is older than an RPi3, i’d recommend against turning mode a/c decoding on.
Rpi3 and later i wouldn’t expect it to be an issue.
