PyQt4 or QtRuby - memory comparison

Well, this is another Python vs Ruby article, hope it is useful.
Today I have measured memory consumption of QtRuby against PyQt4. quite similar scripts were used in both tests and the results are here:

Python 3.3           - 11,040K  / 19,456K shared memory
Python 2.7.3        - 10,056K  / 19,008K shared memory
Ruby 1.9.3p327  -   9,380K  /  21,660K shared memory

The memory consumption is very similar too. Writing the code in QtRuby is more pleasant though.

and here are the sources:
Python:


import sys
from PyQt4.QtCore import *
from PyQt4.QtGui import *

if __name__ == "__main__":
  app = QApplication(sys.argv)
  widget = QWidget()

  widget.setWindowTitle("Hello QtPython xxxx")
  widget.resize(200,100)

  button = QPushButton("Quit")
  button.clicked.connect(QApplication.quit)

  label = QLabel("Hello Qt in the Python way!")

  layout = QVBoxLayout()
  layout.addWidget(button, 0, Qt.AlignCenter)

  layout.addWidget(label, 0, Qt.AlignCenter)

  widget.setLayout(layout)

  widget.show()
  sys.exit(app.exec_())

Ruby:



require 'Qt4'

Qt::Application.new(ARGV) do
    Qt::Widget.new do

        self.window_title = 'Hello QtRuby v1.0'
        resize(200, 100)

        button = Qt::PushButton.new('Quit') do
            connect(SIGNAL :clicked) { Qt::Application.instance.quit }
        end

        label = Qt::Label.new('<big>Hello Qt in the Ruby way!</big>')

        self.layout = Qt::VBoxLayout.new do
            add_widget(label, 0, Qt::AlignCenter)
            add_widget(button, 0, Qt::AlignRight)
        end

        show
    end

    exec
end
