The fastest cron for ripple you’ll never need.

A bit of explaination here:

Ripple uses a cronjob to fix any eventual errors in the database. For doing it, it used cron.php, a terribly performing script. No, really. That’s three minutes of server CPU being used at 100%!

So I decided to rewrite it to be better performant, and what better language to do it if not Go (well, C, C++ and Assembly are indeed faster, but I’m not on that level of insanity).

This is the result: (watch the video especially for the last 30 seconds, as you can see the true power of ripple-cron-go).


Assuming you have Go installed and your GOPATH set up

go get -u
cd $GOPATH/src/
go build
nano cron.conf
./ripple-cron-go # Boom!


This is an example of a very simple unit of ripple-cron-go:

package main

import (


func opTimeConsumingTask() {
	defer wg.Done()

	color.Green("> TimeConsumingTask: done!", count)

Then you would add a bool in the config struct to enable/disable the task, then this to cron.go (cron.go contains main())

	if c.TimeConsumingTask {
		verboseln("Starting time consuming task")
		go opTimeConsumingTask()
