[DUG] EMBARCADERO MY GRIPE

[John Bird]

Lets hear some Delphi Android benchmarks and file sizes  (I understand they are not so small)

Hi Jolyon, 

It seems that we are going through the benchmark way :-)

I tried to run the app in the url you mentioned and it crashed. 

How about you look at this url? http://magenic.com/Blog/Post/4/Mobile-Development-Platform-Performance

My work is getting data from server which is similar to test 3.
java version shows 2.369s and xamarin version shows 1.738s in that url. That is around half seconds difference.

I sometimes got around less than 70ms round trip time in my own test to get data from server in sydney, Australian in north shore, Auckland, nz if the server is not busy. That is amazing fast using Xamarin android. 

Most customers are in Australia. I guess that they might get around 50ms round trip time.

Regards

Leigh

  As for Xamarin performance, consider the source.  By which I don't mean the code, I mean who is making what claims.

  Any advantage is only seen in an Intel Android VM.  On ARM (by far the most prevalent in terms of actual Android hardware), Dalvik beat Xamarin almost every time, until Xamarin.Android 4.7.11.

  What is odd about this is that these results are from 2013, over a year after Xamarin posted their claims about astonishingly superior performance vs Dalvik.  It is interesting that Xamarin do not disclose what environment their benchmarks were run in.  Also interesting that they do not compare themselves to ART which is the more relevant comparison going forward.

  In any event, I don't think there is any chance that Google will drop ART any time soon (they already dropped Dalvik) in favour of a Mono based implementation of Android.  ;)

    Hi Jolyon, 

    I mentioned to you before in the thread. If google choose to use mono framework in android, xamarin apk size can reach several kb too. The reason for me to use Xamarin is the app developed by Xamarin using mono framework is faster than dalvik before ART time. The load time for the app is not my main concern. I care about the speed running the app for whole lifecycle. Here is the url https://blog.xamarin.com/android-in-c-sharp/

      What a fabulous attitude.  It's thanks to that sort of thinking that we now "need" machines with quad core 2.5GHz processors and 8GB of RAM just to run frikkin MS Word.​
