Hello All,I was reading David's post and found it very interesting. I tested on a RPi2B and did not get the results that David posted. At first, I thought the Pillow was taking all of time. My question, what would taking all of time? These are the steps that I used. Testing pypy on RPi2B jessie >From the site below http://pypy.org/download.html Python2.7 compatible PyPy 4.0.1 https://bitbucket.org/pypy/pypy/downloads/pypy-4.0.1-linux-armhf-raspbian.tar.bz2 wget https://bitbucket.org/pypy/pypy/downloads/pypy-4.0.1-linux-armhf-raspbian.tar.bz2 bzip2 -d pypy-4.0.1-linux-armhf-raspbian.tar.bz2 cd /opt/ sudo tar xvf /home/pi/pypy-4.0.1-linux-armhf-raspbian.tar Needed to install myhdl in pypy cd ~/myhdl/ sudo /opt/pypy-4.0.1-linux-armhf-raspbian/bin/pypy setup.py install Needed to install pip in pypy wget https://bootstrap.pypa.io/get-pip.py sudo /opt/pypy-4.0.1-linux-armhf-raspbian/bin/pypy get-pip.py Needed to install Pillow in pypy sudo /opt/pypy-4.0.1-linux-armhf-raspbian/bin/pypy -m pip install Pillow ls /opt/pypy-4.0.1-linux-armhf-raspbian/site-packages/ easy_install.py _markerlib myhdl-1.0dev-py2.7.egg-info Pillow-3.1.0.dist-info pip-8.0.2.dist-info README setuptools-19.6.dist-info wheel-0.26.0.dist-info easy_install.pyc myhdl PIL pip pkg_resources setuptools wheel Testing the times to run with python & pypy time python test_top.py --test real 0m8.363s user 0m8.210s sys 0m0.080s time /opt/pypy-4.0.1-linux-armhf-raspbian/bin/pypy test_top.py --test real 0m40.811s user 0m38.620s sys 0m0.480s I created a version that did not use the Image libtime python nopil_test_top.py --test real 0m7.943s user 0m7.790s sys 0m0.140s time /opt/pypy-4.0.1-linux-armhf-raspbian/bin/pypy nopil_test_top.py --test real 0m26.320s user 0m26.060s sys 0m0.220s As before the pypy took longer than the python one. It appears that the Image reading only took less than .5 sec. Did I fail to do something?https://github.com/develone/jpeg-2000-test/tree/master/pc_fast_blinker_jpeg Do you not get the benefit, until you exceed the time, to convert the python to compiled? Initially I was only testing a few values. To do the complete image the test bench will grow very quickly.
