Thread: Re: [ubl-lcsc] Processing Efficiency Test WAS Re: Position Paperon List Containers
Greetings

I've just tried a quick test.

I used instant saxon to run a very simple transformation with two draft 8 invoice instances both with 1000 lines - 
test.xml being the no-containers version and test1.xml being exactly the same but with InvoiceLineList as a container of the invoice lines (no time spent ensuring this was valid as I took saxon to be schema-agnostic). My stylesheet was just extracting the buyer party name into a simple piece of HTML.

The output below does show a 50% reduction in processing time with the single list container for the invoice lines. 

I only ran it a few times because there was no doubt about the figures.

I've attached the stylesheet and both xml instances.

Now of course it still leaves the matter of how much importance should be placed on processing speed in comparison to other considerations when processing speeds are constantly improving. My main concern remains the possibility that remains in my mind of reduced reusability with the containers - but I for one don't need further convincing of the rather surprising improvement in performance exactly as Arofan stated.

All the best

Stephen Green
