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

[Niall G. <gal...@ya...>]

Hi,
 
Ill take a look at this. It seems very strange that it would spend 44% of its time on this method. Perhaps the profiler you are using is a sampling profiler, and it simply has not got enough samples to determine where the time is being lost accurately. At any rate I will look in to it. The problem I have had with profiling is that Simple uses a lot of recursive algorithms, so profiling by method visits etc is not very useful. I will try to write some tests to profile individual non-recursive parts separately, perhaps there are some gains to be made, likely with reflection I would think, but also with how the schema is constructed and used internally.
 
Thanks,
Niall

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


Hello, 

I am having performance issues in Android parsing a very large XML file.

Profiling trying to find where the bottleneck is, if I undestood correctly, the application is 44% of the time in the function "KXmlParser.getLineNumber", called from PullReader$Start.<init>, but looking at its source code it seems to only read an instance variable an nothing more.

Can someone shed a light on this?

I don't know it posting images is allowed here, so I uplodaded to an image sharing site:
