Make Ubuntu packages 90% faster by rebuilding them

TL;DR

You can take the same source code package that Ubuntu uses to build jq, compile it again, and realize 90% better performance.

Setting

I use jq for processing GeoJSON files and other open data offered in JSON format. Today I am working with a 500MB GeoJSON file that contains the Alameda County Assessor's parcel map. I want to run a query that prints the city for every parcel worth more than a threshold amount. The program is

slav

package main

import "fmt"

func f(c chan func() (int, string)) {
	c <- (func() (int, string) { return 0, "s" })
}

func main() {
	c := make(chan func() (int, string))
