[DUG] EMBARCADERO MY GRIPE

[Leigh Wanstead]

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
