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.

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.

Environment

Tests were run in VMware Fusion 2.0.6 virtual machine, 512 MB RAM, Microsoft Windows Sever 2003 R2 (Standard Edition, Service pack 2).
Host machine is MacBook Pro, 2.4 GHz Intel Core 2 Duo, Mac OS X 10.6.2, 4 GB RAM.

>ruby -v

Mail version 1.3.4 on all platforms.

I had to click a h4 headline.

<h4 id="addproject">Create a new project</h4>

This did not work.

browser.h4(:id, "addproject").click

I posted a question to wtr-general mailing list and Bret Pettichord suggested to extend Watir with this, so it would support h4 headlines.

module Watir
  class H4 < NonControlElement
    TAG = 'H4'
  end
  module Container
    def h4(how, what)
      return H4.new(self, how, what)
    end
  end
end

Now this works.

browser.h4(:id, "addproject").click

I had to click a h4 headline.

<h4 id="addproject">Create a new project</h4>

This did not work.

browser.h4(:id, "addproject").click

I posted a question to wtr-general mailing list and Angrez Singh was kind enough to help.

This will click h4 headline.

browser.element_by_xpath("//h4[@id='addproject']").click
