Subject Profiler accuracy
Date Sun, 21 May 2006 16:13:52 GMT

I am using the cocoon profiler to debug my pipelines. I found the 
results to be very inaccurate, especially when I use transformers that 
rely on DOM documents (I use dom4j documents but the functionality is 
very similar to the AbstractDOMTransformer from cocoon).

These components often show very short processing times, which are 
wrong, as time measures within the transformer show. The total time is 
about 30% greater than the cummulated durations of the various pipeline 

Maybe this has something to do with the buffering behavior of DOM based 

Is there any way to improve the accuracy of the profiler?

BTW, can I somehow tell the profiler to show the whole URI instead of 
the current sitemap uri. Especially when using flow I have different 
sitemaps, but all use the same pipeline name. So there is no way to see 
which sitemap processed the pipeline because the profiler does only show 
the local sitemap URI. Any ideas?
