RE: measuring bulk performance & turn around times of

More than a given processors performance I am interested in figuring out
the performance or efficiency of a certain XSL that has included
N-number of modular XSL files which internally have a bunch of templates
etc. 

Basically I am currently using .NET & MSXML 4.0. More than measuring the
XSLT engines performance, I am interested in ways that one can MAP
metrics around the following:
- the XML file that is fed into) and 
- the nested XSLs that are used to transform this XML file (or XML
files). 

In essence, I want to be measuring the XSL efficiency versus the XSLT
processors efficiency. 

Thanks,

Abhishek

I would be very careful about only doing that. There are a lot of
startup 
costs in most XSLT processors that cause problems with one shots tests.
You 
almost certainly need to use a custom driver that matches how you would
like 
to use the processors to get accurate figures. 

If its WIN32 only, the Microsoft recommendation used to be carry on
using 
MSXML (via COM) as the .NET XSLT was still under development. Of the
publicly 
available processors MSXML always comes very high up the benchmarks. If
you 
want more performance you need to look at the companies that specialize
in 
XML appliances and/or do some code tuning.

I have spent a fair amount of time comparing XSLT processor performance
so 
feel free to ask some detailed questions. I also have access to pretty
much 
the full range of processors if there is some standalone bit of XSLT you
are 
interested in getting figures for.
