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.
