Benchmarks: What new things does iOS 9 enable in Pythonista?

JonB

I suspect this has an awful lot to do with what other apps are open, whether or not you have internet turned on and thus whether background processes are going on, etc.

@JonB , true. I normally have a lot of apps running in the background. I closed them all down. I didn't restart the iPad though. Then with timeit i was getting consistent 6.33xxx. Also turned off mobile data and wifi. That made no difference still around 6.3xxx. Each time I shut down Pythonista before running timeit.

@smath , with the exact same code as yours on iPhone 6s, I get the following
Darwin-15.0.0-iPhone8,1-32bit
4.09668588638
Darwin-15.0.0-iPhone8,1-32bit
1.13581109047
Darwin-15.0.0-iPhone8,1-32bit
1.13619184494

First timing is with pythonista unloaded. Then subsequent timings just running after loaded

iOS 9.0.2

Pystone might also be interesting for benchmarking. It's included in the beta, so you can simply run

from test import pystone
pystone.main()

(if you're not in the beta, you can simply copy/paste the pystone module I linked above, it's a single file.)

I recently got my new iPhone 6s, and the performance improvements are quite remarkable. I now get pretty much exactly the same result as on my (2012) MacBook Pro, i.e. around 115,000 pystones/second. On the iPad Air 2, it's around 60,000.

With pystone same as @omz
iPad Air 2, 128gb, iOS 9.02 (62,000)
IPhone 6s 128gb, iOS 9.02 115,00

I will be interested to try in on my Mac Pro

Old screenshot, the OS has been updated of course

Wow, only got this on my MacPro.

/System/Library/Frameworks/Python.framework/Versions/2.7/bin/python2.7 /Users/ianjoicey/PycharmProjects/untitled1/main.py
Pystone(1.1) time for 50000 passes = 0.525893

Process finished with exit code 0

I am pretty sure it was run without debugging. Seems very slow compared to the other numbers.

Well I'm using Pythonista on my iPad running an HTTP Server script to serve HTML (also edited in Pythonista) as (localhost) to Safari running in iOS 9 Slide Over mode.

This is functioning as (a basic but) nice sidebar for augmenting text. For example wrapping text in quotes, composing Markdown links from text+URL.

It's basic now; It might not be so basic later on.

Not sure if this counts as the 1 iOS 9 element is I'm targeting Slide Over (which IS new in 9). And I'm doing it from Pythonista.

Pystone for iPad Pro, 128gb , wifi/cell iOS 9.1

Pystone(1.1) time for 50000 passes = 0.35624
This machine benchmarks at 140355 pystones/second

thats a nice increase

New iPad Pro 12.5' , time for new benchmark :) I had to run with 2.7, the map object in Pystone apparently does support subscripts in 3.x something. I didn't know how to fix, so I just ran with python 2.7

It seems like @omz had a test built in before, but that looks like it's gone.

My test below is a single run with Pythonista started fresh

My mythical iPad is looking pretty good so far :)

@Phuket2 I tested with Python 3. I think Python 2 is still faster in most benchmarks.
