Ruby Mail on CRuby, JRuby and IronRuby

by Željko Filipin

Today I tried Mikel Lindsaar's Mail gem on CRuby, JRuby and IronRuby.

Installation of each Ruby version and Mail gem was really easy so I will not describe it here. What interested me was how fast was Mail on each Ruby implementation.

I have created a simple mail and saved it as 1.eml.

From: from@test.com
To: to@test.com
Message-ID: <4b336e9e762a0_a1014263a4689d3@2003-ie7.mail>
Subject: This is a test email
Mime-Version: 1.0
Content-Type: text/plain;
charset="US-ASCII";
Content-Transfer-Encoding: 7bit

Some text for mail body

This script will read the file, display subject and time elapsed (in seconds).

time = Time.now
require "rubygems"
require "mail"
mail = Mail.read("1.eml")
puts mail.subject.to_s
puts Time.now - time

I have executed the script three times for each Ruby implementation. It looks to me that CRuby and JRuby are similar in speed, and IronRuby is way slower.

Test Run CRuby JRuby IronRuby
1 2.594 3.0 9.8125
