     55The following picture is a 'load graph' from a server with a large crontab, launching many jobs at different frequency, from every minute to every month. Of course, sometimes jobs overlap badly, and if they compete for a scarce ressource (such as I/O on a local disk) they are slow and also slow down the whole server.
