WiPy 1.0 firmware v1.8.6 release 1.20 x v1.8.2 release 1.30

Comparing WiPy 1.0 firmware v1.8.6 release 1.20 versus firmware v1.8.2 release 1.30 :

• to work with PyMakr, WiPy 1.0 needs MicroPython v1.8.2 release 1.30, available in :
  https://github.com/wipy/wipy/releases
• MicroPython v1.8.2-1.8.6 downloads in :
  http://micropython.org/download#wipy
  don't contain firmware release 1.3.0, just the 1.2.0 release;
• MicroPython v1.8.6 release 1.20 has serious performance issues compared to MicroPython v1.8.2 release 1.30 :

• pystone_lowmem "benchmark" of 239 x 659;
• PerformanceTest (using "time.ticks_ms") benchmark :
  https://github.com/micropython/micropython/wiki/Performance
  of 175218 x 918031;
• ADC sample rate of 14.4 ksamples/s x 62.5 ksamples/s.

To know the release version of MicroPython on WiPy :

MicroPython v1.8.2-103-g834e021 on 2016-08-19; WiPy with CC3200
Type "help()" for more information.
>>> import os
>>> os.uname()
(sysname='WiPy', nodename='WiPy', release='1.3.0', version='v1.8.2-103-g834e021 on 2016-08-19', machine='WiPy with CC3200')

I don't know the reason for this low performance of v1.8.6, maybe is the release 1.2.0.

Anyway, it would be nice to have MicroPython downloadswith release 1.30 for WiPy 1.0.

Link for the same issue in MicroPython forum.

@livius See the topic with benchmark, where there are links to download the files, so you can test yourself.

@daniel
slower yes, but if above stats are true
then difference is too big

Hello,

Please use our latest release on the WiPy repository while we sync all the changes to the MicroPython repository.

The reason for the performance differences on the 1.2.0 version is because that one has threading enabled and release 1.3.0 hasn't. Threading adds extra overhead which explains the slower performance.

Cheers,
Daniel
