Description

My machine is an Intel P4, 800MHz, 512MB ram
Linux and Windows behaviour is similar

I'm transforming a relatively large source document (5MB)
xalan-J version 2.2 only takes a few seconds
xalan-J versions after 2.2, including 2.4-D1 take more than a minute

Profiling shows that almost all the time is spent before the actual
transformation takes place (I assume its spent building the DOM).

Behaviour is consistent from JDK 1.1 through JDK 1.3. I could not reproduce the
problem with JDK 1.4, even when trying to override bootclasspath to use the
newer xalan versions instead of the ones provided.

If anybody wants to look into this, please contact me and I'll provide the
relevant stylesheet and XML source.
