Re: [Simple-support] Android performance - strange profiling

[Robert M. <rob...@gm...>]

I just started doing timing tests on my XML and I discovered that on an
ASUS Transformer (Original) that a 31 line XML file took 2 seconds to load
and a 219 line xml file took around 2.8 seconds to load. Those times are
quite large, it is obviously preferably if we could cut them by about a
fifth. I suspect that the massive amounts of branching contribute to the
delay somewhat but more investigation needs to be done. Niall probably also
knows what the cause of the problems are.

I will be looking into it soon. I my goal would be to get the entire
process down to 0.5 seconds on an Android device for any file that has 1000
lines or less. Maybe the reflection code also causes quite a bit of a
slowdown. We shall see. I wonder how much of the reflection calls get
cached as the parsing goes along.
