#2> What happens if you grab the jq source code from Launchpad, then configure and rebuild it with no flags at all? Even that is about 2-4% faster than the Ubuntu binary package.
Why wouldn't that be identical?

#3Surprised it would be 90%. Are the packages all debug symbols?
I recall trying with march=native and seeing some improvement, but not enough to care at a system level.

If I had the time to fork jq, I would convert the relevant part to C++ so it doesn't spend literally all of its time dynamically allocating strings it is just about to discard.
