Hi,

Hi, on a Nokia N800, platform with a 400 MHz CPU and 128 MB RAM, Android m3-rc37 is quite responsive. Instead the last version, m5-rc15h is slow, I think because in the boot process launchs more services and so uses nearly all the RAM memory, and maybe because all the debug function in the binary application framework are active.

Andrea, thanks for your answer!

IIRC, the current Dalvik VM is interpreted, not a JIT, which means that performance is going to be abysmal.

That was my thought also...

Note that in almost all of the demos that have been shown, what you have seen is the Dalvik interpreter running on about the same class of hardware: 350MHz CPU, 128MB RAM.

Yes, but the demos were made with acceptable applications. I was really wondering if an application similar to Quaqe for example will run smoothly on Android (from what I know Quaqe is native code right now). Secondly, the guidelines page (http://code.google.com/android/ toolbox/performance.html) advise the user not to write highly object- oriented code so my presumption is that these kind of applications won't run very fast on Android.
