Thanks very much for collecting this data. It reveals that generate-id() in
Saxon, when using the "tinytree" tree model and a large source document, is
extremely (and quite unnecessarily) inefficient. This will be fixed!
A couple of points about the measurements:
- if you were using Instant Saxon, you were using Microsoft Java, not JDK
1.3 as stated. JDK 1.3 is generally 2-3 times faster.
- you can get timings from Saxon by using -t on the command line.
Saxon 6.1 shouldn't make any difference in this area.
