For example I use a ruby script as an output filter for incoming mails (ie: it takes a mail coming on an adress, uses ActionMailer to parse it and then process it)... There can be one such mail coming each second during peak hours. With MRI it works fast enough, with JRuby I'll have to use a daemon either by tranforming the script into a SMTP server or by using Nailgun. Lionel
