Re: myhdl with cython?

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

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/

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.
