[DUG] EMBARCADERO MY GRIPE

[Leigh Wanstead]

Hi Jolyon,

If network round trip time has little or nothing to do with framework, how
you explain that url get different time from different framework? I will
assume that they will get similar time spent to get data on all framework.

Dalvik platform is slow which is agree by google. Dalvik is slower than
Sun's jdk on mobile platform I read somewhere on internet. The
consideration for dalvik is not speed, but app size.

Regards
Leigh
