Title: Dump1090-fa wisdom.local file
Post by: JayM on August 02, 2021, 11:02:29 AM
I replaced dump1090-mutability with dump1090-fa, built from source code on Debian Linux. The github page at https://github.com/flightaware/dump1090 mentioned generating a "wisdom.local" file by typing in a terminal in the source's directory make wisdom.local and adding the command-line switch --wisdom /path/to/wisdom.local to dump1090-fa-s startup command-line switches, which I did. My messages received count has at least doubled but I don't understand what dump1090-fa's "wisdom" is about, how it works or what it does. Can anyone shed any light on the wisdom thing?

Looks like you have already posted on FlightAware site.

Does this answer your question?

Yes, sorry. It occurred to me some time after I'd already posted here that it would be better to ask on FlightAware's discussion page as it's their software. To summarize, the "wisdom" routine basically benchmarks dump1090 on your computer, finds the optimal settings for your CPU, and writes them to the wisdom.local file. This makes dump1090 run as efficiently as possible on your system.
