MonoDroid Speed

Iโ€™m thinking about switching to MonoDroid, the problem in the trial version only allows me to check my code in the emulator, and everything works more slowly in the emulator. my question is (before I pay $ 400), is the compiled code fast enough when deployed to the device itself?

Performance after launching the application (~ 3 s) is very good in Nexus One and is not like trying to run on an emulator.

Performance on the device is also good for me. Sometimes even faster than Dalvik. But yes, in the beginning there is a 2-3 second lag.

( "" , MonoDroid, :))

I see much more 2-3 second lag at startup. That is, the time when I click on the application (and the log shows an ActivityManager starting my activity) when it is called OnCreate.

I see 5 seconds or more on my HTC Legend with Android 2.2 (about 2 years). For instance:

The slowness is due to the Android emulator - working on a real device is great for MonoDroid.
