Apologies if you get this twice. The original does not seem to have reached

saxon API

I'm sorry, I don't understand. How can you have a comma-separated list of
queries, when a query can contain a comma? And I don't understand why you're
having difficult measuring the execution time: what technique are you using?

You might find it useful to look at the source code of net.sf.saxon.Query.
This has an undocumented option -3, which causes the query to be executed
three times, displaying the timings for each execution.
